With the 1.0 update for TCG Card Shop Simulator arriving on September 15, 2026, the Tetramon cards previously used for shop inventory become fully playable. The update brings the Tetramon Duel Master TCG to Xbox Series X|S and PC, allowing players to engage in competitive matches within their own stores.
Setting Up Your Duel
Matches are governed by a specific set of rules to ensure consistent play:
- Deck Building: Every deck must contain exactly 50 cards, with a limit of four copies per named card.
- The Opening Hand: Players draw five cards. If the hand is unfavorable, you may take one mulligan by placing your current hand at the bottom of the deck and drawing a fresh five.
- Guardian Area: Before play begins, place the top four cards of your deck face-down in the Guardian Area. These cards remain inaccessible until your Tamer Points decrease.
- Starting Health: Each duelist begins with 500 Tamer Points.
Battle Mechanics and Elemental Zones
The game board features four Elemental Areas: Fire, Earth, Water, and Wind. Where you position your Tetramon is critical, as a card’s total Attack Power is the sum of its own stats and the power of the Elemental Area it occupies.
During the Main Phase, you may play one Tetramon into any Elemental Area. Doing so triggers the card's Play Effect immediately. Note that each Elemental Area only holds one Basic Tetramon at a time; playing a new card into an occupied slot will clear the previous one.
Evolution and Combat
Evolution allows you to power up your board after your initial setup:
- Evolution Chains: Evolution cards must be stacked directly on top of the corresponding base Tetramon.
- Turn Delay: You cannot evolve a Basic Tetramon on the same turn it is played. Once the card has been on the board for one turn, you may chain multiple evolutions in a single turn if you have the cards in your hand.
- Attack Phase: You may begin attacking once your setup is complete, though the first turn of the duel skips the Attack Phase entirely.
