This elegant loop turns the modular mechanics of modern Rooms into a permanent-copying machine by leveraging Fractured Realm's static ability to double up on triggered effects. When Marina Vendrell taps to unlock Mirror Room, that triggered ability fires twice instead of once, flooding your board with a pair of Kelpie Guide token copies. From there, the two Kelpie Guide tokens take turns untapping Marina, allowing her to repeatedly lock and unlock the door to trigger the copy effect infinitely many times. Roar of Resistance rounds out the ensemble by granting your newly generated army haste, ensuring that once you are done manipulating your rooms, your infinite tokens are ready to immediately overwhelm the board.
