Mardu Siegebreaker + Aggravated Assault + Rose Room Treasurer

Mardu Siegebreaker

Aggravated Assault

Rose Room Treasurer

How it works

1. Declare Mardu Siegebreaker as an attacker, triggering its second ability, creating a token copy of Rose Room Treasurer tapped and attacking each opponent.
2. When the Rose Room Treasurer tokens enter the battlefield, they each trigger for each other token that entered the battlefield, and any other Rose Room Treasurer(s) you control trigger for each token that entered the battlefield.
3. Resolve a Rose Room Treasurer trigger, creating a Treasure token if its the first or second time that ability has resolved this turn, or choosing not to pay otherwise.
4. Repeat step 3 for each remaining trigger.
5. Move to your postcombat main phase.
6. Activate five Treasures by tapping and sacrificing them, adding 3.
7. Activate Aggravated Assault by paying 3, causing you to untap all creatures you control and to get an additional combat and main phase after this one.
8. Repeat.
