Earthcraft + Wild Growth + Sliver Queen

Earthcraft

Wild Growth

Sliver Queen

How it works

1. Activate Sliver Queen by paying 2, creating a creature token
2. Activate Earthcraft by tapping the creature token, untapping the basic land that has Wild Growth attached.
3. Activate the land by tapping it, adding 1
4. Wild Growth triggers, adding 1
5. Repeat

This charming loop turns a humble forest into an engine of creation by exploiting the way Earthcraft interacts with mana-producing enchantments. By tapping the Sliver Queen token you just made to untap your land, you generate enough mana through Wild Growth to cover Sliver Queen's activation cost and still come out ahead. Because Wild Growth turns a single tap into extra green mana, you generate an excess of resources with every iteration, letting you flood the board with an endless army of Sliver tokens.
