Ygra, Eater of All + Camellia, the Seedmiser + Grinding Station

Ygra, Eater of All

Camellia, the Seedmiser

Grinding Station

How it works

1. Activate Grinding Station by tapping it and sacrificing any other creature.
2. Because the creature is a Food due to Ygra, when it dies, Camellia and Ygra trigger.
3. Resolve the Ygra trigger, putting two +1/+1 counters on it.
4. Resolve the Camellia trigger, creating a 1/1 Squirrel creature token.
5. When the Squirrel enters the battlefield as a Food due to Ygra, Grinding Station triggers, untapping Grinding Station.
6. Resolve the Grinding Station ability from step 1, causing target player to mill three cards.
7. Repeat.
