Ramos, Dragon Engine

Colored mana turned into fixing: cast anything with pips and this Dragon fattens itself, then cashes five counters for the whole rainbow of doubled mana in a single burst. That trade rate is the tension the card lives inside. Feeding it wants multicolored spells, since a two- or three-color card stacks multiple counters at once, but every counter you build is a counter you might rather leave on the body than spend. The payout is deliberately lopsided: ten mana across all five colors is enough to hard-cast almost anything, but only once per turn, and only after you have paid the front-loaded tax of assembling a five-counter reserve. It reads as a mana artifact wearing a creature's body, and the flying 4/4 base is not incidental: a fixing engine that can also close a game changes how much you can afford to sink into activations, because the counters were never dead stats even if the ability sits idle. The design predates the current fashion for five-color counter payoffs by a long stretch, and it shows in the honesty of the math: there is no exile, no death trigger, no spectacle cost hidden in the text, just cast spells, grow, and convert. What balances it is the removal of the counters themselves. Every rainbow burst shrinks the Dragon back toward death range, so the card forces a running choice between mana and survival that never fully resolves.
