Hierophant Bio-Titan

A 12/12 for twelve mana is a curve-topper by default, but Frenzied Metabolism is the mechanic that decides whether it lands three turns early or never. The printed cost reads punishing until you see the payoff structure it sits inside: a green counters deck spends a game building +1/+1 counters across its board, then cashes them in as an alternate resource to slam this out at a discount, shrinking the creatures that fed it in exchange for a single body that towers over them. Every counter removed makes the cast cheaper but weaker everywhere else on your side, which turns the pivot into a timing decision: keep growing your board wide, or collapse it into one payoff that Titanic keeps unblockable by anything with power 2 or less. Vigilance and reach mean the swing costs you no defensive turn, and ward taxes the removal that would otherwise punish the all-in. The design inverts how green usually treats counters: instead of permanent stat growth banked toward a wide board, they become spendable fuel that converts into cost reduction, a one-time exchange of breadth for a single overwhelming threat. The gamble is legibility. It looks like a big dumb finisher and plays like a resource-conversion engine, which is exactly why its ceiling outruns the printed cost, and its floor is a creature you were never going to hardcast at full price anyway.
