Fist of Suns

The trade it offers is brutal on paper and quietly liberating in practice: replace whatever a spell costs with one mana of every color, no more and no less. For a Lightning Bolt that math is laughable; for the things players actually want to cheat into play, it collapses an arbitrary mana value into a fixed five-color tax. That fixed point is the whole appeal. Anything with a backbreaking cost (a colorless titan, a double-faced bomb, a spell whose printed number runs into double digits) becomes castable the moment you can produce one of each color, which is a problem five-color decks were already solving. The artifact does nothing to fix the mana itself; it just rewrites the bill into a denomination those decks happen to keep on hand. It also predates much of the design space it now exploits, so its best targets are cards printed long after it: each new generation of expensive, color-light haymakers makes a stale three-mana artifact look sharper. The catch is the floor, not the ceiling. Drop it on an empty board with the wrong lands and it sits inert, a tax collector with nothing to collect. Pair it with a manabase that taps for five colors trivially and it stops being an enabler and starts being a license to ignore the cost line entirely, a permission cheap permanents were never supposed to hand out.
