Earthcraft + Mondrak, Glory Dominus + Sliver Queen

Earthcraft

Mondrak, Glory Dominus

Sliver Queen

How it works

1. Activate Sliver Queen by paying 2, creating two creature tokens due to Mondrak.
2. Activate Earthcraft by tapping a creature token, untapping a basic land
3. Activate the land by tapping it, adding 1.
4. Repeat steps 2 and 3 one additional time.
5. Repeat from step 1.

This magnificent loop relies on a clever loop of activation, mana-generation, and token multiplication. You begin by activating Sliver Queen to manufacture your initial population, which is immediately doubled by Mondrak, Glory Dominus to ensure an abundant supply of material. From there, you tap those newly minted tokens to fuel Earthcraft, continuously untapping a basic land to generate the precise amount of mana needed to sustain the queen's activation cost. Because Earthcraft only requires a creature to tap—and cares not whether it is a basic land or a Sliver—the engine feeds itself infinitely, resulting in endless creature entry triggers and a massive army of tapped Sliver tokens.
