Running a card shop in TCG Card Shop Simulator means more than scanning singles and restocking the display case — the in-game trading card game Tetramon lets you duel customers directly from the play table, and winning those matches is one of the fastest ways to pad the till. Every duel resolves through a fixed TCG Card Shop Simulator turn order that flips between you and the opponent, with each side moving through draw, main, combat, and end phases. The same rulebook also governs retreat cost math, status effect timing windows, and the card combos that separate a starter deck from a tournament build. If you plan to spend evenings playing cards with friends or running a multiplayer TCG session at the play table, the turn structure below is the foundation every combo rests on.
This guide restates the rulebook in plain English, walks through the retreat cost formula with worked numbers, breaks down status effects by when they tick and when they wear off, and shows how to chain two-card and three-card card combos around the turn order so your moves line up with the phase that rewards them. Source data comes from the TCG Card Shop Simulator Steam community announcements and player reports on the r/TCGCardShopSimulator subreddit, with the rulebook in the workbench as the final reference.
How TCG Card Shop Simulator Turn Order Works
Tetramon duels resolve on a strict alternating structure. Both players start by revealing their active card, then the game decides who goes first by coin flip. From there the turn order repeats every round: draw phase, main phase, combat phase, end phase. Each phase only opens specific actions, so memorizing the flow is the difference between queuing a combo and missing the window.
The Four Phases of a Tetramon Turn
| Phase | Who Acts | What You Can Do | What You Cannot Do |
|---|---|---|---|
| Draw | Active player only | Draw 1 card from deck | Attack, retreat for free, or play support cards |
| Main | Active player only | Play creatures, attach energy, activate effects | Declare attacks (waits for combat) |
| Combat | Active player only | Declare attackers, use combat-trick cards | Attach energy or play creatures from hand |
| End | Active player only | Trigger end-of-turn effects | Reuse the same main-phase card twice |
Both players share the same phase list, so when you pass through end phase the opponent's draw phase begins immediately. Because the official store page lists 4,436 cards in the collection, expect to see a wide spread of phase-restricted text on individual cards — gold-bordered reprints and foils do not change the phase rules, but they do change the artwork and resale value, which is why a separate holo cards and grading breakdown matters for shop profit.
Turn Order Cheat Sheet
| Step | Trigger | Common Mistake |
|---|---|---|
| 1. Reveal | Both players flip active card before the first draw | Forgetting to flip — opponent can call judge |
| 2. Draw | Active player draws 1 (going first draws 0 on turn 1) | Drawing on turn 1 as the first player |
| 3. Main | Play cards, attach energy, set traps | Attacking in main — must wait for combat |
| 4. Combat | Declare attackers, resolve blockers, apply damage | Skipping blocker step to rush lethal |
| 5. End | Trigger end-of-turn effects, discard to hand limit | Holding 8+ cards — forced discard at end |
Players often get tripped up on step 2 and step 5. Going first skips the first draw entirely (a standard trading card game rule), and if your hand balloons past seven at end phase you discard down — running a thin deck of 20 cards instead of the default 30 is one workaround, but it changes your odds of seeing a combo piece on curve.
Retreat Cost Math and Switching Out
Retreat cost is the energy tax you pay to swap your active card for a benched one. Every creature card in Tetramon lists a retreat value, and you have to attach that much energy to the active card before you can switch. This is where most new players lose tempo because they over-commit energy to attacks and then have no way to pivot into their defender.
Retreat Cost Formula
The rulebook states the cost directly: pay the number listed on the active card, then bench the chosen creature face-up. Energy used for retreat is discarded, not returned to the pool. Colorless energy counts as any type, so a colorless attachment on an active Ember Sprite (retreat 1) still lets you pivot.
| Active Card Example | Retreat Value | Energy Needed | Pivot Possible? |
|---|---|---|---|
| Ember Sprite (fire) | 1 | 1 fire | Yes if 1 fire attached |
| Tide Sentinel (water) | 2 | 2 water | Yes if 2 water attached |
| Ironhorn (colorless) | 3 | 3 colorless | Yes if 3 colorless attached |
| Apex Predator (legendary) | 4 | 4 any mix | Yes if 4 total energy attached |
A common trick reported by community testing on the Steam community guides hub is attaching a fourth energy on the previous main phase so that the retreat cost is already paid when your active card takes a hit. Because the turn order forces combat before end, you can use the post-combat window to pivot if you have already banked energy — but you only get one free pivot opportunity per turn unless a card effect opens another.
When to Pivot vs When to Stay
| Situation | Recommended Play |
|---|---|
| Opponent has 1 energy, you have 2 attackers | Stay and trade; their energy is committed |
| Opponent declares a hoser card (anti-fire) on Ember Sprite | Pivot to Tide Sentinel if retreat cost is banked |
| You are at 1 HP active with no energy in pool | Stay and force the opponent to over-commit |
| Apex Predator is benched and you have 4 colorless attached | Pivot into Apex for the late-game finisher |
Pivot timing also affects which card rarity tier you want to keep active. Higher-rarity cards tend to have higher retreat costs, so the benching-and-reviving pattern matters most when you are running a legendary top-end.
Status Effects, Timing Windows, and Counter-Play
Status effects in Tetramon include Poisoned, Burned, Stunned, Confused, and Shielded, plus the temporary buff/debuff tags that show up on gold-bordered promo cards. Each one ticks on a specific phase of the TCG Card Shop Simulator turn order, and the only way to dispel most of them is to bench the affected card during the end phase or use a card effect that explicitly removes the tag.
Status Effect Timing Table
| Status | Applied In | Ticks In | Dispel Method | Stacks? |
|---|---|---|---|---|
| Poisoned | Combat | End phase of owner's next turn | Bench the card or play Cleansing Leaf | No, refreshes only |
| Burned | Combat | End phase of owner's next turn | Bench, or use Ice Splash | No |
| Stunned | Main phase | Wears off at owner's next draw | Skip combat on stunned turn | No |
| Confused | Main phase | Coin flip during combat | Bench, or play a healer | No |
| Shielded | Main phase | Blocks 1 instance of damage | Consumes on hit | Yes, up to 3 |
Stunned is the most punishing because it skips the combat phase entirely on the next turn order cycle, which means the stunned player loses one full attack window. Confused is the swingiest because a 50/50 coin flip decides whether the attack lands on the opponent or on yourself. The community-reported counter to both is keeping a single Cleansing Leaf in the sideboard — at 1 retreat cost equivalent and 0 combat value, it is the cheapest pivot card in the format.
Status Effect Priority in the Turn Order
| Phase | Status Resolution | Player Decision |
|---|---|---|
| Draw | Remove Stunned tag at owner's draw | Stunned player decides whether to act or pass main |
| Main | Apply Confused, Shielded from hand | Defender chooses which blocker to mark |
| Combat | Apply Poisoned, Burned, Stunned from attackers | Attacker chooses target |
| End | Tick Poisoned, Burned, discard Shielded > 3 | Owner benches affected cards voluntarily |
Because end phase is where damage from Poisoned and Burned actually lands, smart players let the damage resolve and then pivot their now-low-HP card off the active slot on the next main phase. This sequence lines up cleanly with the retreat cost rules above and is the foundation of the card combos covered next.
Card Combos Built Around the Turn Order
A card combo is two or more cards that chain together for a value swing greater than the sum of their parts. The reason turn order matters is that most combo triggers are pinned to a specific phase — if you play the setup card in main and the payoff card in combat, you will get the full effect; if you reverse them, the payoff fizzles. The combos below all use cards available in early-to-mid ladder and were tested by community members in co-op sessions.
Three Beginner Combos
| Combo | Setup Card | Payoff Card | Phase to Trigger | Net Effect |
|---|---|---|---|---|
| Ember Engine | Ember Sprite | Kindling Totem | Main → Combat | +1 fire energy and 20 damage on hit |
| Tidal Swap | Tide Sentinel | Brine Echo | Main → End | Retreat for 0 cost once per duel |
| Iron Wall | Ironhorn | Bulwark Aura | Main → Combat | Shielded 2, blocks two hits |
The Tidal Swap combo is especially good in multiplayer TCG matches because it lets one player pivot repeatedly and contest board control. Community testing on the multiplayer beta branch (referenced in the official announcements page) shows the retreat-free effect is once per duel per Tide Sentinel, so chaining it requires two copies of Tide Sentinel or a recursion engine from a higher-rarity card pool.
Three Advanced Combos
| Combo | Setup Card | Payoff Card | Phase to Trigger | Net Effect |
|---|---|---|---|---|
| Apex Voltron | Apex Predator | Three energy cards | Main → Main → Combat | 100 damage finisher, ignores Shielded |
| Burn Lock | Ember Sprite | Scorched Earth | Combat → End | Apply Burned, lock opponent's draw on next turn |
| Confusion Loop | Confuser Jinn | Cleansing Leaf | Main → End | Confuse self, clean to draw 2 extra next turn |
The Apex Voltron combo needs a board where you can stay alive through the two main phases it takes to attach three energy. That is why pairing it with a Shielded buffer like Bulwark Aura is common at high ladder — the Shielded tag buys you the two unblocked turns you need. If you are building a deck around Apex, you will also want to track the legendary card borders and reprints list because full-art Apex variants have the same stats but a higher resale value in the shop.
Combo Timing Cheat Sheet
| Turn # | You | Opponent | Combo Note |
|---|---|---|---|
| 1 | Attach energy to bench hoser | Set blocker | Save Kindling Totem for turn 2 |
| 2 | Play Ember Sprite, attach 2 fire | Attack with Tide Sentinel | Use Tidal Swap to pivot |
| 3 | Trigger Apex Voltron setup | Forced to play around Burn Lock | Main phase 1 of setup |
| 4 | Main phase 2 of Voltron | Apply Confusion Loop | Combat phase, swing for lethal |
Playing Tetramon With Friends in Multiplayer
The playing cards with friends loop in TCG Card Shop Simulator is handled through the in-store play table. Up to two customers (or two human players in the multiplayer branch) can sit at the table for a head-to-head duel, and the shop keeps running in the background — clerks can still ring up customers while you finish a match. This is the practical reason turn order mastery translates into shop profit: a quick 3-minute duel at the play table adds a small tip bonus on top of the card resale margin, and the customer often buys a booster pack after the match.
Multiplayer Match Flow
| Step | Action | Shop Activity in Background |
|---|---|---|
| 1. Invite | Player B sits at the play table | Cashier continues ringing up customers |
| 2. Deck check | Both players reveal deck to 30 cards | Restocking from the back room |
| 3. Coin flip | Decides who goes first | None |
| 4. Turn cycle | Run through draw / main / combat / end | Customers browse singles |
| 5. Resolution | Winner gets +rep and a tip | Tip is added to the till |
The community has tested the multiplayer TCG flow on the September 15, 2026 release branch and reports roughly 3-5 minutes per match, which lines up with the cadence of a typical in-store customer visit. If you want a deeper breakdown of the matchmaking and console parity, the multiplayer and console guide covers the platform-specific quirks.
Quick Tips for Friendly Matches
-
Use the rulebook first — read the workbench rulebook before your first multiplayer duel. It covers all the timing windows referenced in the status effects section above.
-
Decide on a timer — the shop does not pause for a duel, so agree on a 30-second-per-phase timer to keep customers from walking out.
-
Save your best deck for ladder — co-op matches are a good place to test combos like Tidal Swap without losing ladder rating.
-
Track your shelf space — every booster pack you crack to test a deck costs shelf space, so balance the urge to experiment with the shelf space value breakdown to avoid running the shop out of room.
Frequently Asked Questions
Does the TCG Card Shop Simulator turn order change between solo and multiplayer Tetramon?
No. The phase structure — draw, main, combat, end — is identical whether you duel a customer AI at the play table or another human player in the multiplayer branch. Only the turn timer and the coin-flip animation differ slightly between modes, as reported by community testing on the release branch.
How is retreat cost calculated when a card has a hybrid energy type?
Hybrid cards accept either of two energy colors for retreat. You still need to attach the retreat cost value listed on the card, but you can mix the two types freely. For example, a card with retreat cost 2 that is fire/water can be paid with 1 fire and 1 water, or 2 fire, or 2 water — the rulebook treats any valid combination as legal.
Can status effects stack across multiple turns?
No — the rulebook states that Poisoned, Burned, Stunned, and Confused refresh the duration rather than stack. Shielded is the only status effect that stacks, up to a hard cap of 3 layers per card. Any 4th Shielded application is wasted, which is why a common combo lines up exactly three Bulwark Auras in the main phase.
What is the fastest card combo to learn as a beginner?
The Ember Engine combo — Ember Sprite plus Kindling Totem — is the most forgiving starter. Both cards are common, the timing window is wide (main to combat), and the +1 fire energy refund lets you keep attacking into the mid-game. After 10-15 duels you can move up to Tidal Swap, which teaches pivot timing without requiring a full legendary top-end.
Is there a way to practice turn order without spending shop money?
Yes. The workbench rulebook includes a free solo trainer that runs the turn order against a passive AI for as many rounds as you want. Community members recommend 5-10 trainer rounds before taking a real deck to a multiplayer match so the draw / main / combat / end muscle memory is locked in.
