Yenna, Redtooth Regent + Instill Energy + Faith Healer

Yenna, Redtooth Regent

Instill Energy

Faith Healer

How it works

1. Activate the mana-producing creature by tapping it, adding at least 2.
2. Activate Yenna by paying 2 and tapping it, creating a token copy of Instill Energy attached to the mana-producing creature, then untapping Yenna and causing you to scry 2.
3. Activate the Instill Energy token by paying 0, untapping the mana-producing creature.
4. Activate Faith Healer by sacrificing the Instill Energy token, causing you to gain 1 life.
5. Repeat.

This clever loop turns Yenna, Redtooth Regent into an endless enchantment factory by leaning heavily on the free activation of Instill Energy. Because Instill Energy can untap its enchanted creature once each turn, you can repeatedly copy it with Yenna to refresh Yenna's ability while churning through your library with infinite scrys. Meanwhile, Faith Healer provides a clean exit strategy by sacrificing the cloned Auras to secure infinite life.
