Plague Engineer

Most anthems that scale by creature type ask you to commit at deckbuilding and hope the opponent showed up with the tribe you guessed. This one reads the board first: it names its target on entry, so you pick the word that hurts most after seeing what is across the table, whether that is a swarm of tokens sharing a subtype or a synergy pile all keyed to one name. The -1/-1 is a static effect rather than a one-shot, so it keeps shrinking freshly-made copies for as long as the body stays in play: a persistent tax on any strategy that wins by flooding the board with creatures of one type. That the reduction touches only opponents' creatures is the quiet clause that lets it live in a shell running its own tribe. Deathtouch is not filler either. A 2/2 that trades up in combat means the enforcer does not have to die to a chump block, and it punishes anything sent to kill it, so an opponent has to spend real removal to unstick the effect rather than simply blocking it away. It is a hatebear built for a recurring problem in any large card pool: the go-wide token and tribal decks that show up whenever the format's answers thin out, met here by a design that clamps the whole board and dares them to attack into it.
