Earthcraft + Sliver Queen + Groundchuck & Dirtbag

Earthcraft

Sliver Queen

Groundchuck & Dirtbag

How it works

1. Activate Sliver Queen by paying 2, creating a creature token
2. Activate Earthcraft by tapping the creature token, untapping a basic land.
3. Activate the land by tapping it, adding 1
4. Groundchuck & Dirtbag triggers, adding
5. Repeat

This elegant engine relies on Earthcraft to turn any basic land into an untapped mana source by tapping your creatures, neatly solving the steep mana requirements of Sliver Queen's token-making ability. As you pump out 1/1 Sliver creature tokens with the Queen, Earthcraft lets you tap those fresh tokens to untap your land for the two mana needed to keep the loop going. Meanwhile, Groundchuck & Dirtbag sits quietly in play providing a crucial mana-boosting static ability, turning that tapped land into a green mana bonus on top of its normal production. Together, this trio generates an endless swarm of creature tokens and enters-the-battlefield triggers to overwhelm your opponents.
