Basri's Lieutenant + Metallic Mimic + Blasting Station

Basri's Lieutenant

Metallic Mimic

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing another creature with a +1/+1 counter on it.
2. When the creature dies, Basri's Lieutenant's second ability triggers, creating a 2/2 Knight creature token that enters the battlefield with a +1/+1 counter due to Metallic Mimic.
3. When the Knight enters the battlefield, Blasting Station triggers, untapping itself.
4. Resolve the Blasting Station ability from step 1, dealing 1 damage to any target.
5. Repeat.

This loop turns a simple drafting of troops into a relentless artillery barrage by weaponizing the interaction between your permanents' permanent static boosts and death triggers. You start by sacrificing a creature to Blasting Station, which triggers Basri's Lieutenant because that fallen creature carried a +1/+1 counter. As the resulting 2/2 Knight enters, Metallic Mimic ensures it arrives with an essential +1/+1 counter already in place, which simultaneously triggers Blasting Station's untap ability. This leaves you with a fresh creature that can immediately be fed back into Blasting Station, allowing you to cycle through endless sacrifices until your opponents are entirely decimated.
