Doppelgang + Echo Mage + Pestermite

Doppelgang

Echo Mage

Pestermite

How it works

1. Cast Doppelgang by paying 6, targeting Pestermite and a mana-producing permanent.
2. Holding priority, activate Echo Mage by paying and tapping it, copying Doppelgang, targeting Pestermite and a mana-producing permanent.
3. Resolve the copy of Doppelgang, creating two copies of Pestermite and the mana-producing permanent.
4. When the Pestermite tokens enter, they trigger, untapping Echo Mage and any other applicable permanent.
5. Holding priority, activate the two mana-producing permanent tokens by tapping them, adding at least .
6. Repeat from step 2.

This fascinating loop transforms a massive initial mana investment into an unstoppable engine of replication and untapped potential. Once Echo Mage reaches its ultimate level, it provides the spell-copying machinery needed to supercharge Doppelgang. As Doppelgang resolves to multiply both Pestermite and your chosen mana-producing permanent, the fresh Pestermite tokens trigger to untap your board—including Echo Mage and your newly minted mana sources. By looping this process, you continuously feed the mana back into Echo Mage to copy yet another Doppelgang, generating endless creature tokens, landfall triggers, and an astronomical surplus of mana.
