The five-color tutor as a single payoff: pay the full and you walk away with five specific spells, one of each color, assembled in one search. The eight mana value and the rainbow cost are the whole bargain. Cheaper tutors fetch one card; this one names a complete kit at the moment of casting, and the price is that you cannot cast it until every color of mana is online, a structural commitment most decks never make. The constraint is built into the search itself: one white, one blue, one black, one red, one green, no doubling up on the color you actually want. That rules out splashing for the effect; it only pays out in a deck genuinely organized around touching all five colors. And because lands are almost always colorless, the search reaches mostly for spells, not a land drop: a combo piece in each color, a removal suite, a finisher plus the answers to protect it, whatever the board demands. Where most card-advantage spells hand you raw cards and trust you to find the pieces, this delivers the named pieces directly. The reveal clause is the honest cost of that precision: you announce exactly what you are about to do before you do it. It is a maximalist design, an effect that becomes overwhelming the moment it resolves, but one that asks for the most disciplined manabase in the game just to reach the casting.
