Chandra, Flame's Fury

Every ability here points at the same thing: damage, and lots of it. This is the rare planeswalker with no card advantage, no token generation, no board development in its kit; it plows all six mana into raw burn output. The plus builds loyalty while still throwing two damage anywhere it wants, so it climbs without ever going purely defensive. The minus-two is the workhorse, a removal spell that also chips the opponent's life total, and it leaves enough loyalty behind to plus again the following turn. That cadence matters: a planeswalker that can activate a two-damage plus and a four-damage minus on alternating turns is a slow burn spell that also happens to demand an answer, since ignoring it means eating two to the face every turn while it climbs. The ultimate folds a board wipe and a haymaker together, ten to a player and to each creature they control, the sort of number that ends the game on resolution rather than promising to. The whole card reads as a study in what a planeswalker looks like when it commits entirely to one axis: no engine, no protection, just a loyalty total converting itself into damage over as many turns as the opponent lets it live.
