Flesh // Blood

This Jund split is the cleanest demonstration of fuse as a self-contained engine: the two halves load and fire the same gun. Flesh exiles a creature card from any graveyard and stacks +1/+1 counters equal to its power onto a target creature; Blood then asks that swollen body to deal damage equal to its power to any target. Cast both in one turn and you have graveyard-fueled burn whose magnitude is set by the fattest thing that has already died, with the damage routed through one of your own creatures rather than coming off the stack. The design works because each half earns its keep alone: Flesh converts a dead creature's power into a living one's stats, a reanimator-adjacent buff that never returns the body; Blood is a creature-cannon in red and green that fires without committing to combat. Fuse rewards paying the full combined cost rather than taxing it. Blood is where the design opens up: it lets a creature throw its power as direct damage without attacking, sidestepping blockers, combat triggers, and the entire combat step, so a sufficiently large body becomes burn that ignores the board. Build the counters with Flesh first and the source can be enormous, because the damage scales with the size of what has died, not with the spell itself. A two-card combo printed on a single card.
