Rat King, Verminister + Thornbite Staff + Belonging + Bloodflow Connoisseur

Rat King, Verminister

Thornbite Staff

Belonging

Bloodflow Connoisseur

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 Bloodflow Connoisseur by sacrificing Belonging.
4. When Belonging dies, Rat King triggers, untapping Rat King.
5. Resolve the Bloodflow Connoisseur 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.

This loop relies on an intricate cycle of sacrifice and recursion, fueled by the changeling tokens from Belonging that instantly satisfy Rat King, Verminister's heavy activation cost. By feeding Belonging to Bloodflow Connoisseur, you trigger Rat King's vanishing act to bring Belonging right back to the battlefield, endlessly generating new bodies and death triggers. Although the step-by-step instructions trace the active sequence, it is Thornbite Staff lying quietly in wait that truly makes this infinite—its static ability catches every single dying creature and immediately untaps the wielder, keeping Rat King ready to repeat the entire devastating loop.
