Ratadrabik of Urborg, Samwise the Stouthearted, and Carrion Feeder

Prerequisites

• Ratadrabik of Urborg on the battlefield
• Samwise the Stouthearted on the battlefield
• Carrion Feeder on the battlefield

Steps

1. Activate Carrion Feeder 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 Carrion Feeder ability from step 1, putting a +1/+1 counter on it
5. Repeat

Results

• Infinite +1/+1 counters on Carrion Feeder
• Infinite death triggers
• Infinite ETB
• Infinite LTB
• Infinite sacrifice triggers
