Together Forever + Ashnod's Altar + Walking Ballista + Urza, Lord Protector

Together Forever

Ashnod's Altar

Walking Ballista

Urza, Lord Protector

How it works

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

This loop turns a modest investment into an unstoppable engine by leveraging cost reduction and sacrifice value. With Urza, Lord Protector on the field lowering spell costs, Walking Ballista can be cast for just a single mana with a single +1/+1 counter. You then use Ashnod's Altar to sacrifice Walking Ballista for two colorless mana, which easily funds the activation of Together Forever's ability to return the automaton straight back to your hand upon its death. Repeating this cycle loops the Ballista endlessly to generate boundless sacrifices, leaves, and storm count.
