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

All permanents on the battlefield (Auton Soldier as a copy of Adrix and Nev on the battlefield).

You have at least two opponents. Auton Soldier does not have summoning sickness.

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 for each Treasure sacrificed this way.

Resolve the next Rose Room Treasurer trigger, choosing to pay to deal X damage to any target.

Repeat steps 5 and 6 as desired for each remaining trigger.
