Blade of the Bloodchief + Triskelavus + Krark-Clan Ironworks

Blade of the Bloodchief

Triskelavus

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing another creature, adding CC.
2. When the creature dies, Blade of the Bloodchief triggers, putting a +1/+1 counter on Triskelavus.
3. Activate Triskelavus by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Triskelavite artifact creature token.
4. Repeat.
5. Once you have infinite colorless mana, you may instead use the Triskelavite token's ability to sacrifice it, dealing infinite damage to any target(s).

This loop turns Triskelavus into an infinite mana and damage engine by carefully recycling its own parts through Krark-Clan Ironworks. Whenever you spend a counter to spin out a Triskelavite token, Blade of the Bloodchief steps in to replace that lost counter—and then some—whenever that token or another creature goes to the graveyard. By feeding those tokens and creatures right back into Krark-Clan Ironworks to generate colorless mana, you sustain the loop, grow Triskelavus endlessly, and ultimately redirect all those sacrificed tokens into a barrage of infinite damage against any target.
