How it works
Cast Lumra by paying 4.
When Lumra enters, it triggers.
Holding priority, activate Troubled Healer by sacrificing a land.
Repeat step 3 until you control no lands.
When you sacrifice the last land, Lumra will die as a state-based action due to having 0 toughness.
Resolve the Lumra trigger from step 2, causing you to mill four cards and return all lands from your graveyard to the battlefield tapped.
When the lands enter, Emeria Shepherd triggers that many times.
Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning Lumra from your graveyard to the battlefield.
