Wormfang Drake + Yahenni, Undying Partisan + Metamorphosis Fanatic

Wormfang Drake

Yahenni, Undying Partisan

Metamorphosis Fanatic

How it works

1. Cast Wormfang Drake by paying its mana cost.
2. When Wormfang Drake enters, its first ability triggers, exiling Metamorphosis Fanatic.
3. Activate Yahenni by sacrificing Wormfang Drake.
4. When Wormfang Drake dies, its second ability triggers, returning Metamorphosis Fanatic from exile to the battlefield.
5. When Metamorphosis Fanatic enters, it triggers, returning Wormfang Drake from your graveyard to the battlefield.
6. When Wormfang Drake enters, its first ability triggers, exiling Metamorphosis Fanatic.
7. Resolve the Yahenni ability.
8. Repeat from step 3.

This clever loop relies on a recursive dance between Wormfang Drake and Metamorphosis Fanatic to continuously cycle each other in and out of play. When Wormfang Drake enters the battlefield, its triggered ability exiles Metamorphosis Fanatic, and when Metamorphosis Fanatic returns the favor upon its own entry, it pulls the Drake right back out of your graveyard. Meanwhile, Yahenni, Undying Partisan acts as the perfect catalyst for this cycle, using its sacrifice ability to feed the loop at instant speed while growing ever larger with +1/+1 counters.
