Angrath's Ambusher
A 2/3 for three that reads as a 4/3 the moment a very particular planeswalker is on the board, and the gap between those two bodies is the entire point. The buff is a static conditional keyed to controlling an Angrath, of which there are only a handful, so the bonus power sits behind a deckbuilding commitment the creature cannot fulfill on its own. Strip the condition away and the stats are honest but forgettable; satisfy it and you have a beater that trades up in combat. Because the modifier is static rather than triggered, the body simply reads larger while the Angrath holds and shrinks back the instant it leaves, which ties the card's value directly to your ability to protect that planeswalker. This is a payoff printed to give a walker-and-tribe theme its ground troops: the "the boss makes the crew hit harder" reward that exists to make a marquee planeswalker feel like the anchor of a deck rather than a standalone card. The flavor lands cleanly, a pirate standing taller under a captain's command, but as construction it is exactly what it appears to be: a single-key payoff, worth assembling only by a deck that already wanted that key for its own reasons.
