Ojer Taq, Deepest Foundation // Temple of Civilization | Auton Soldier | Rose Room Treasurer

Cards

Declare
Auton Soldier as an attacker.
Auton Soldier's myriad ability triggers, creating nine token copies of itself as a nonlegendary copy of
Ojer Taq attacking each other opponent.
When the
Auton Soldier tokens enter the battlefield,
Rose Room Treasurer triggers that many times.
Resolve the first two triggers, creating 2*3^(the number of
Ojer Taqs you control) Treasure tokens.
Holding priority, activate any number of Treasure tokens by tapping and sacrificing them, adding ({1} magic symbol) for each Treasure sacrificed this way.
Resolve the next
Rose Room Treasurer trigger, choosing to pay ({X} magic symbol) to deal X damage to any target.
Repeat steps 5 and 6 as desired for each remaining trigger.
