Dragon Hunter

Hatebears live or die on whether the threat they answer is actually in the room, and this one names the most telegraphed possible target. A 2/1 for one white mana is already a serviceable aggressive body; the two lines of rules text turn it into something a single named tribe cannot get through. Protection from Dragons means combat damage from a Dragon is prevented, a Dragon's removal cannot target it, and a Dragon cannot block it: so an attacking copy walks past the creatures it would otherwise have to race, and a defending one holds off a Dragon without taking a scratch. The reach clause is the load-bearing companion to the protection. Without it, a one-toughness ground creature simply watches Dragons fly over its head, and protection alone prevents the damage but never stops the attack from reaching a planeswalker or getting through unblocked. Granting reach in the same breath lets the body sit back and turn away one five-mana flier a turn, eating nothing while a bomb accomplishes nothing. The catch is the same thing that makes it tidy: every word of value is contingent on the opponent fielding the named creature type. Against a board without Dragons it is a vanilla 2/1, a rate the rest of any white curve outclasses. This is sideboard logic written into a maindeckable creature: a card that does nothing remarkable until the matchup it was drawn for arrives, at which point a single white pip stonewalls a creature that cost five times as much.
