Aragorn, the Uniter
Four colors, four triggers, one payoff engine that keys off the single most common thing you do in Magic: cast a spell. The design conceit here is that each color's contribution is exactly the thing that color already wants to do (white makes a body, blue smooths draws, red points burn at a face, green pumps for lethal), so the card rewards you not for building a synergy but for simply playing all four colors and firing off spells in sequence. What makes the engine cohere rather than sprawl is that the four triggers overlap in a single combat step: cast a green spell to make a creature a threat, cast a red spell to chip the opponent while their blockers are outclassed, and every white spell along the way widens the board the green pump can amplify. The scry-2 on blue is the quiet glue, filtering toward whichever color you need next. A 5/5 for four mana across four colors is already an aggressive rate, and the real cost is the manabase: the card demands you actually assemble all four colors to unlock the full loop, and it does nothing extra for the colors you fail to cast. That constraint is what keeps a "cast a spell, get value" body from being oppressive; it is a commander that punishes the greedy manabase it insists on.
