Eternity Vessel + Dragonspark Reactor + Fate Transfer + Karn, Silver Golem

Eternity Vessel

Dragonspark Reactor

Fate Transfer

Karn, Silver Golem

How it works

1. Activate Karn twice by paying 2, causing Eternity Vessel and Dragonspark Reactor to become artifact creatures until end of turn.
2. Cast Fate Trasnfer by paying 1U/B, moving all counters from Eternity Vessel onto Dragonspark Reactor.
3. Activate Dragonspark Reactor by paying 4 and sacrificing it, dealing damage equal to the number of charge counters on it to an opponent and up to one target creature.
4. The opponent loses the game due to having 0 or less life.

This fascinating engine begins with Karn, Silver Golem, whose ability animates both your noncreature artifacts into temporary creatures so they can interact with counter manipulation. Once animated, Fate Transfer acts as the bridge that sweeps up all the charge counters accumulated on Eternity Vessel—counters normally tied to your life total—and dumps them in one massive pile onto Dragonspark Reactor. With its reservoir instantly overflowing with counters, you simply activate Dragonspark Reactor to sacrifice itself and unleash a devastating, lethal wave of damage directly at your opponent.
