Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + X-23, Deadly Weapon + Bloodflow Connoisseur

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

X-23, Deadly Weapon

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing the other Mutant.
2. When the Mutant dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When the Mutant enters, X-23 triggers, putting a +1/+1 counter on X-23 and the other Mutant.
4. Resolve the Bloodflow Connoisseur ability.
5. Repeat.
