Together Forever + Ashnod's Altar + Marketback Walker + Armor Wars

Together Forever

Ashnod's Altar

Marketback Walker

Armor Wars

How it works

1. Cast Marketback Walker by paying 1, causing it to enter the battlefield with a +1/+1 counter on it.
2. Activate Together Forever by paying 1, targeting Marketback Walker.
3. Activate Ashnod's Altar by sacrificing Marketback Walker, adding CC.
4. When Marketback Walker dies, Together Forever triggers, returning Marketback Walker from your graveyard to your hand.
5. Repeat.

This clever loop turns the modular mechanics of Marketback Walker and Together Forever into a self-sustaining engine. By using Ashnod's Altar to sacrifice the Walker and generate the colorless mana needed to fund Together Forever's protective activation, you can endlessly recur the creature for a constant stream of triggers. While Armor Wars isn't strictly necessary for the mana-neutral loop to function, its presence on the battlefield takes full advantage of the swirling artifact activity to draw cards and hurl damage at your opponents.
