Orah, Skyclave Hierophant + Sister Hospitaller + Valiant Changeling + Goblin Bombardment

Orah, Skyclave Hierophant

Sister Hospitaller

Valiant Changeling

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Valiant Changeling.
2. When Valiant Changeling dies, Orah triggers, returning Sister Hospitaller from your graveyard to the battlefield.
3. When Sister Hospitaller enters, it triggers, returning Valiant Changeling from your graveyard to the battlefield and causing you to gain 7 life.
4. Resolve the Goblin Bombardment ability.
5. Activate Goblin Bombardment by sacrificing Sister Hospitaller.
6. When Sister Hospitaller dies, Orah triggers, allowing you to return a Cleric with mana value 5 or less from your graveyard to the battlefield.
7. Resolve the Goblin Bombardment ability.
8. Repeat.

This infinite loop relies on a clever recursion chain between Orah, Skyclave Hierophant and Sister Hospitaller, with Goblin Bombardment serving as both the sacrificial outlet and the win condition. Orah's passive trigger lets you continuously recur cheaper Clerics whenever a Cleric dies, allowing Sister Hospitaller to slip right back onto the battlefield and use its own entry ability to bring back Valiant Changeling. Because Valiant Changeling counts as every creature type thanks to changeling, it safely qualifies as a Cleric under Orah's watchful eye while also providing the hefty mana value needed to fuel the loop and net you plenty of life along the way.
