Ekthi, Contaminator Priest + Sword of the Meek + Krark-Clan Ironworks

Ekthi, Contaminator Priest

Sword of the Meek

Krark-Clan Ironworks

How it works

1. Cast Sword of the Meek by paying 2.
2. When Sword of the Meek enters, its living weapon ability granted to it by Ekthi triggers.
3. Holding priority, activate Krark-Clan Ironworks by sacrificing Sword of the Meek.
4. Resolve the Sword of the Meek trigger, creating a 0/0 Phyrexian Germ creature token. It'll enter as a 1/1 due to Ekthi's static effect.
5. When the Phyrexian Germ enters, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Phyrexian Germ.
6. Repeat from step 2.

This ingenious loop relies on turning Equipment into self-contained factories using Ekthi, Contaminator Priest, which grants Sword of the Meek the living weapon ability so it enters with a token to attach to. That created token enters as a 1/1 thanks to the passive power boost from Ekthi, Contaminator Priest, which in turn triggers Sword of the Meek's own recursion ability to pull itself right back out of the graveyard. By feeding Sword of the Meek to Krark-Clan Ironworks along the way, you generate an endless surplus of colorless mana while effortlessly cycling the sword through your graveyard and onto the battlefield over and over again.
