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

Adrix and Nev, Twincasters

Auton Soldier

Rose Room Treasurer

How it works

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