Yenna, Redtooth Regent + Airtight Alibi + Careful Cultivation + Faith Healer

Yenna, Redtooth Regent

Airtight Alibi

Careful Cultivation

Faith Healer

How it works

1. Activate Yenna by paying 2 and tapping it, creating a copy of Airtight Alibi attached to Yenna, and then untapping Yenna and causing you to scry 2.
2. When the Airtight Alibi token enters, it triggers. Holding priority, activate Yenna by tapping it, adding .
3. Resolve the Airtight Alibi trigger, untapping Yenna.
4. Activate Faith Healer by sacrificing the Airtight Alibi token.
5. Repeat.

This clever loop turns Yenna, Redtooth Regent into an endless duplication factory by taking advantage of the unique way Airtight Alibi untaps its target upon entering. Because Yenna can copy the Aura and instantly untap herself when it enters, she sets up a perpetual motion machine that lets you repeatedly churn out copies. You can then feed those extra copies to Faith Healer to gain boundless life, or weave in mana from Careful Cultivation to fuel the entire engine while filtering your deck with endless scrys.
