Free fan-made tools for the Grand Archive TCG: a browser simulator for online and hotseat play, a proxy generator that turns decklists into printable PDFs, and a rules assistant for questions about rules and card interactions. Not affiliated with, endorsed by, or approved by Weebs of the Shore LLC.
Create a lobby from the home page and share the game code or invite link with your opponent. Each player imports a decklist, and the game runs in the browser with no account or install needed. To play both seats on one device, switch the lobby to hotseat mode.
The proxy generator turns a decklist into a print-at-home PDF with cards at official size, intended for casual playtesting before you buy real cards. Proxies are not legal in sanctioned tournament play. See the legal page for the full proxy-use policy.
Damage on a champion is marked with damage counters that stay until removed (for example by Recover). When a champion's damage counters equal or exceed its life, that champion dies, and a player who controls no champions loses the game. A player also loses if they attempt to draw from an empty main deck; an empty deck by itself is not a loss. If both champions die in the same state-based check, the game is a draw.
A turn follows six phases in order: Wake Up, Materialize, Recollection, Draw, Main, and End. In a two-player game, the first player skips their first Wake Up, Materialize, Recollection, and Draw phases and begins in their Main phase (and can't attack on that first turn); the second player skips their first Wake Up, Materialize, and Recollection phases and begins with their Draw phase.
Activation plays a main-deck card from your hand by paying its reserve cost: you place that many other cards from your hand face-down into your memory zone. Materialization plays a material-deck card by paying its memory cost: that many cards are banished from your memory zone, selected at random. You may only materialize one card per materialize phase unless an effect gives you permission for more.
Cards you reserve to pay costs go from your hand into the memory zone face-down, and they return to your hand during your Recollection phase. Memory costs work differently: they banish randomly selected cards from your memory zone. So reserved cards cycle back to you each turn unless something spends or banishes them first.
An object on the field is awake when upright and rested when turned horizontal. Awake champions and allies must rest as a cost to attack, and the rest symbol on a card usually marks resting as the cost of an ability. During your Wake Up phase, the game wakes every rested object you control as a turn-based action that can't be responded to.
