Rat King, Verminister

Thornbite Staff

Belonging

Woe Strider

How it works

1. Cast Belonging by paying 5.
2. When Belonging enters, it triggers, creating three 1/1 Shapeshifter creature tokens with changeling.
3. Activate Woe Strider by sacrificing Belonging.
4. When Belonging dies, Rat King triggers, untapping Rat King.
5. Resolve the Woe Strider ability.
6. Activate Rat King by tapping it and sacrificing the Shapeshifters.
7. When the Shapeshifters die, Rat King triggers three times, untapping Rat King.
8. Resolve the Rat King ability from step 5, returning Belonging from your graveyard to the battlefield.
9. Repeat from step 2.
