OFFICIAL TRADING CARD GAMEPLAYBOOKTHE FOUR PHASES
Build
Set eligible Mascots, boost through the required stages and freely rearrange your field Mascots at no cost. You may discard or replace field Mascots with eligible cards from your hand during Build or End. AMP, MAX and REQ requirements still apply. Newly played Mascots may be boosted immediately when eligible.
Raid
Each eligible Raiding Mascot may raid once per turn unless a card says otherwise. Compare RP with RP or DEF to resolve combat. If the values are equal, both Mascots are destroyed unless a card effect protects them. Raid a Shard Card through an undefended lane to claim it. Place claimed Shard Cards in the Shard Pile to your left; claimed Mascots can be set during your Build or End Phase. Assist and Quick Save cards follow their printed timing and conditions.
End
You may still play legal Assist cards and activate eligible effects after your Raid Phase. You may also set eligible Mascots, switch field positions and boost during End Phase, following the same costs and requirements as Build. Resolve end-of-turn effects, then end your turn. Empty your opponent’s Vault to win.
