Jaheira, Friend of the Forest + Ant Queen + Anointed Procession + Shang-Chi, Master of Kung Fu

Jaheira, Friend of the Forest

Ant Queen

Anointed Procession

Shang-Chi, Master of Kung Fu

How it works

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

This dazzling swarm starts with Ant Queen paying one green and one generic mana to make a bug, but thanks to Anointed Procession doubling that output, you actually get two 1/1 green Insect creature tokens instead of one. While those tokens would normally be stuck waiting to tap, Shang-Chi, Master of Kung Fu neatly bypasses summoning sickness by letting you activate creature abilities as though they had haste, while also tapping itself to help pay for the queen's activation. Finally, Jaheira, Friend of the Forest provides the critical engine grease by turning every single one of those newly minted tokens into a mana dork that taps for green, cleanly footing the bill to repeat the cycle indefinitely.
