Sekki, Seasons' Guide + Goblin Bombardment + Queen Allenal of Ruadach
Infinite LTB, Infinite ETB
Activate Goblin Bombardment by sacrificing another creature, targeting Sekki. Sekki will prevent the 1 damage that would be dealt to it and instead removes a +1/+1 counter from it and creates a 1/1 Soldier and a 1/1 Spirit creature token.
Repeat step 1, sacrificing the Soldier, until Sekki dies as a state-based action due to having 0 toughness.
Activate Sekki by sacrificing eight Spirits, returning it from your graveyard to the battlefield.
Repeat.
