Together Forever + Ashnod's Altar + Hangarback Walker + Etherium Sculptor

Together Forever

Ashnod's Altar

Hangarback Walker

Etherium Sculptor

How it works

1. Cast Hangarback 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 Hangarback Walker.
3. Activate Ashnod's Altar by sacrificing Hangarback Walker, adding CC.
4. When Hangarback Walker dies, Together Forever triggers, returning Hangarback Walker from your graveyard to your hand.
5. Repeat.

This clever loop relies on Hangarback Walker as both the fodder and the engine, entering the battlefield with a counter so it can be targeted by Together Forever's activation for just one mana. When you sacrifice Hangarback Walker to Ashnod's Altar, you generate two colorless mana—more than enough to cover recasting it and activating Together Forever again to return it from the graveyard when it dies. Meanwhile, Etherium Sculptor is the secret lubricant that discounts the artifact creature's casting cost, ensuring your mana supply grows with every single iteration.
