Spear Spewer + Dissipation Field + Runaway Steam-Kin + Tuktuk Rubblefort

Spear Spewer

Dissipation Field

Runaway Steam-Kin

Tuktuk Rubblefort

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 looping engine relies on the synergy between Spear Spewer dealing damage to you and Dissipation Field instantly bouncing it back to your hand for reuse, while Tuktuk Rubblefort ensures the newly recast creature immediately loses its summoning sickness by granting it haste. As you repeatedly cast the red spell, Runaway Steam-Kin grows with +1/+1 counters that can be cracked for {R}{R}{R} to endlessly fund the casting cost of Spear Spewer.
