Thornbite Staff + Ashnod's Altar + Pestered Wellguard

Thornbite Staff

Ashnod's Altar

Pestered Wellguard

How it works

1. Activate Pestered Wellguard using the ability granted to it by Thornbite Staff by paying 2 and tapping it.
2. Pestered Wellguard triggers, creating a creature token.
3. Resolve the Pestered Wellguard ability from step 1, dealing 1 damage to any target.
4. Activate Ashnod's Altar by sacrificing the creature token.
5. When the creature token dies, Pestered Wellguard triggers, untapping Pestered Wellguard.
6. Repeat.
