Ill-Tempered Cyclops

Monstrosity was designed to solve a problem common players have always faced: an early-game body that does nothing in the late game. This Cyclops is the mechanic in its plainest form. For four mana you get a 3/3 trampler, an unremarkable beater that asks for nothing; then, once the rest of your hand has run dry, six more mana converts the dead draws into a 6/6 that punches through chump blockers. The trample is the part that matters here, because monstrosity on a creature without evasion just feeds the bigger body into a bigger blocker. Pairing the two means the activation actually translates into damage rather than a stalled board. The cost is the whole tension of the design: at the upgrade is deliberately steep, a mana sink meant to drain the back half of a long game rather than a fair rate you would pay on curve. Like most of the commons that carried monstrosity, this one is built to be ignored early and feared late, a single card that occupies two roles across the arc of a game without ever needing a second spell to do it.
