Resolve both Slimefoot abilities, creating four creature tokens.
Activate Earthcraft by tapping a creature token, untapping a basic land.
Activate the basic land by tapping it, adding 1.
Repeat from step 4 three additional times.
Repeat from step 1.
This clever loop centers around equipping Illusionist's Bracers to Slimefoot, the Stowaway, allowing its token-creation ability to be doubled whenever you activate it. Earthcraft provides the necessary mana and untap mechanics to sustain the engine by turning your newly created tokens into a tap-outlet that untaps your basic lands. Meanwhile, Queen Allenal of Ruadach amplifies your token production by adding a bonus Soldier creature token to every batch, quickly growing into an overwhelmingly massive threat thanks to her own power-boosting static ability.
