Brotherhood Outcast + Viscera Seer + Shade's Form

2. When Brotherhood Outcast dies, Shade's Form triggers, returning Brotherhood Outcast from your graveyard to the battlefield.
3. When Brotherhood Outcast enters the battlefield, it triggers, returning Shade's Form from your graveyard to the battlefield attached to Brotherhood Outcast.
4. Resolve the Viscera Seer ability.
5. Repeat.
