Ratadrabik of Urborg + Altar of Dementia + Samwise the Stouthearted

Ratadrabik of Urborg

Altar of Dementia

Samwise the Stouthearted

How it works

1. Activate Altar of Dementia by sacrificing Samwise.
2. When Samwise dies, Ratadrabik triggers, creating a nonlegendary token copy of Samwise that is a 2/2 Zombie.
3. When the Samwise token enters the battlefield, it triggers, returning up to one applicable card from your graveyard to your hand, and then causing the Ring to tempt you, with the Samwise token becoming your Ring-bearer.
4. Resolve the Altar of Dementia ability from step 1, causing target player to mill cards equal to Samwise's power.
5. Repeat.
