Brotherhood Outcast + Spawning Pit + Minion's Return

Brotherhood Outcast

Spawning Pit

2. When Brotherhood Outcast dies, Minion's Return triggers, returning Brotherhood Outcast from your graveyard to the battlefield.
3. When Brotherhood Outcast enters the battlefield, it triggers, returning Minion's Return from your graveyard to the battlefield attached to Brotherhood Outcast.
4. Resolve the Spawning Pit ability.
5. Repeat.
