The Unbeatable Squirrel Girl + Cryptolith Rite + Fervor

The Unbeatable Squirrel Girl

Cryptolith Rite

Fervor

How it works

1. Activate The Unbeatable Squirrel Girl by paying 1, creating a 1/1 Squirrel creature token for each Squirrel you control.
2. Activate four Squirrels by tapping them, adding 1.
3. Repeat

This delightful loop relies on leveraging the sheer, scampering numbers of your woodland army to fund its own exponential growth. Thanks to Fervor granting your creatures haste, newly hatched tokens don't have to wait around to be useful, and Cryptolith Rite lets them immediately tap for any color of mana to pay the heavy activation cost of The Unbeatable Squirrel Girl's second ability. Because that ability counts *all* Squirrels you control—including the very tokens you just brought into existence—each iteration doubles your forces and yields a net surplus of mana, letting you flood the board with infinite haste-enabled tokens and enter-the-battlefield triggers.
