Ekthi, Contaminator Priest + Sword of the Meek + Phantom Train

Ekthi, Contaminator Priest

Sword of the Meek

Phantom Train

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 Phantom Train 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 clever loop turns graveyard recursion into a self-sustaining engine by uniting Ekthi, Contaminator Priest with the artifact it empowers. Ekthi grants living weapon to Sword of the Meek, so that every time the Sword enters, it brings a fresh 0/0 Phyrexian Germ token along for the ride. Thanks to Ekthi’s static pump, that Germ enters as a 1/1, which immediately triggers the Sword's graveyard clause to loop right back to the battlefield. By slipping Phantom Train into the stack by sacrificing the Sword in response to its own trigger, you bypass the usual destination and start stacking infinite artifact sacrifices, leaving you with an infinitely large, trampling Phantom Train.
