Adrix and Nev, Twincasters | Auton Soldier | Rose Room Treasurer

Cards

Declare
Auton Soldier as an attacker.
Auton Soldier's myriad ability triggers, creating four token copies of itself as a nonlegendary copy of
Adrix and Nev 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^(the number of
Adrix and Nevs you control plus one) 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.
