Armament Master

The math here is the whole pitch: each Equipment on this body grants +2/+2 to every other Kor you control, so a single piece of cheap gear like Kor Outfitter's payload turns a board of 2/2 soldiers into 4/4s, and a second Equipment doubles the bonus again to +4/+4. It is a multiplier that scales on two axes at once, the number of Equipment stapled to it and the number of Kor on the battlefield, which makes it the engine that a low-curve Kor Equipment tribal deck is actually trying to assemble. The exploitable wrinkle is that the buff cares only about Equipment attached to this creature, not the cost or quality of that Equipment: a free or near-free piece does the same work as an expensive one, so the deck wants the cheapest possible gear to equip and the widest possible board to point it at. That same dependency is its honesty. The bonus is anchored entirely to a 2/2 that grants nothing to itself, so a removal spell on the Master deflates the whole team in a single exchange, and an empty hand of Equipment leaves it a vanilla two-drop. Kor as a creature type carried real weight in its home block's tribal architecture, and this is the card that most rewards committing to it fully rather than splashing a few bodies.
