Ironscale Hydra

Green's answer to the question of what happens when your fatty gets chump-attacked into. Most large creatures fear the trade: a bigger blocker, a squad of ground pounders, a race where each combat step chips away at the toughness. This one inverts the math. Anything that swings into it and connects grows it instead of hurting it, and because the ability is a static prevention effect rather than a lifelink trigger or an after-the-fact buff, it sidesteps the usual counterplay of stacking damage past its toughness. You cannot gang-block it into the graveyard through combat, because none of that combat damage ever lands: the prevention replaces it before it can be dealt. The 5/5 body for five mana is deliberately unremarkable on the stat line; the design work is in making it a wall the opponent cannot afford to attack into and cannot profitably block, since blocking is where the counters pile up. The clean way to remove it is noncombat: burn, edicts, exile, wraths that do not route through the combat step. Read as a design, it is a rebuke to the whole logic of trading up with creatures, a fatty that treats combat damage the way most creatures treat healing. In a color that has always leaned on raw size to win the ground, it offers something size alone never could: a body that gets safer the more the board grows around it.
