The Prydwen, Steel Flagship + Sword of the Meek + Chatterfang, Squirrel General + Phantom Train

The Prydwen, Steel Flagship

Sword of the Meek

Chatterfang, Squirrel General

Phantom Train

How it works

1. Cast Sword of the Meek by paying 2.
2. When Sword of the Meek enters the battlefield, The Prydwen triggers.
3. Holding priority, activate Phantom Train by sacrificing Sword of the Meek.
4. Resolve the Prydwen trigger, creating a 2/2 Human Knight and a 1/1 Squirrel creature token.
5. When the Squirrel enters the battlefield, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Soldier.
6. Repeat from step 2.

This clever loop spins up an endless engine using Sword of the Meek as both the catalyst and the recurring sacrifice fodder. As the Sword enters, The Prydwen, Steel Flagship triggers to flood the board with tokens, while Chatterfang, Squirrel General doubles your production by tagging along a 1/1 green Squirrel alongside every Knight. Meanwhile, you can continually sacrifice the Sword to Phantom Train's ability to pump it up with infinite +1/+1 counters, because each time a 1/1 enters, Sword of the Meek's own trigger plucks it right back out of the graveyard to attach itself anew.
