Spear Spewer + Dissipation Field + Runaway Steam-Kin + Akroma's Memorial

Spear Spewer

Dissipation Field

Runaway Steam-Kin

Akroma's Memorial

How it works

1. If Runaway Steam-Kin has three or more +1/+1 counters on it, activate it by removing three +1/+1 counters from it, adding .
2. Cast Spear Spewer by paying .
3. Runaway Steam-Kin triggers, putting a +1/+1 counter on it.
4. Activate Spear Spewer by tapping it, dealing 1 damage to each player.
5. Dissipation Field triggers, returning Spear Spewer from the battlefield to your hand.
6. Repeat.

This loop cleverly turns the self-damage of Spear Spewer into a bounce trigger via Dissipation Field, returning the goblin safely to your hand so you can recast it for a single red mana. Each time you recast that red spell, Runaway Steam-Kin dutifully triggers to stock up on +1/+1 counters, which can then be cracked for three red mana to keep the loop fueled infinitely. Meanwhile, Akroma's Memorial stands watch as a glorious static anthem, granting your creatures haste and keywords that protect them—though the real magic here is simply keeping the engine self-sustaining as you churn through infinite casts and damage.
