Cryptolith Rite + Ant Queen + Fervor + Chatterfang, Squirrel General

Cryptolith Rite

Ant Queen

Fervor

Chatterfang, Squirrel General

How it works

1. Activate Ant Queen by paying 1, creating two creature tokens.
2. Activate the creature tokens by tapping them, adding 1.
3. Repeat

This engine turns a bustling hive into a self-sustaining web of creation by turning every new body into a source of immediate fuel. Thanks to Fervor granting haste and Cryptolith Rite giving your creatures the ability to tap for mana, the Insect tokens from Ant Queen can tap the very moment they enter the battlefield to help pay for the next activation. Meanwhile, Chatterfang, Squirrel General watches over the whole operation, doubling your token output by tagging an extra Squirrel onto every insect born, which conveniently leaves you with a massive surplus of creature tokens and endless enters-the-battlefield triggers.
