Mana Cannons

A payoff that scales with your commitment to gold cards, and one built specifically for the multicolor-matters deck rather than for red aggro. The trigger fires on the cast, not resolution, so the damage happens on the stack before the spell you cast has even done anything: cast a three-color spell and something takes three the moment you announce it, whether or not the spell itself ever resolves. That instant-of-casting window is the wrinkle that separates it from a straight burn engine. It cares only about the color count, so it rewards a deck stuffed with two- and three-color spells over a deck that plays a handful of expensive gold bombs. The reward per trigger is modest by design (a two-color spell buys two damage), but the ceiling is a table full of dead tokens and a chipped-away opponent across a game where you were casting gold spells anyway. What makes it a build-around rather than a splashy include is that the whole return is contingent on your spell density: in a deck light on multicolored cards it is a dead enchantment, and in a deck saturated with them it turns every cast into a small removal spell you were going to play regardless. The color of the spell is irrelevant; only the count matters, which quietly nudges toward the widest wedge or five-color shells where three- and four-color casts are routine.
