Imperial Ceratops

The Enrage mechanic usually pays you in aggression: more damage, more tokens, a spite-trigger that punishes the opponent for blocking or pinging your dinosaurs. This one flips the polarity. Getting hit gains you two life, which turns a 3/5 body into something closer to a stabilizing wall that profits from being attacked into. The toughness is the load-bearing number here: five toughness survives most of the cheap removal and combat that would set off the trigger, so the card invites trades it usually wins, banking life every time something bounces off it. That makes it a defensive Enrage payoff in a mechanic built almost entirely around offense, and the design reads accordingly: where most Enrage cards reward you for swinging a hard-to-block creature into a clogged board, this one asks to sit back and absorb. The interaction it quietly enables is repeatable, controlled damage: any way to deal small amounts of damage to your own creatures (a one-toughness ping, a fight effect that does not kill it) becomes a life-gain faucet, since the Enrage trigger fires on any damage, not just combat. It is a modest rate for a five-mana common, but the role it fills is the unusual part: the lifegain end of a tribe whose other members want nothing more than to bleed the opponent dry.
