Chandra, Heart of Fire

The tension every Chandra planeswalker fights is that a burn-flavored walker wants to close games, but firing a damage ability every turn is slow. This one resolves it by handing you two clocks at once: the plus that pings for two keeps the board and face pressured while ticking loyalty upward, and the plus that dumps your hand to exile three fresh cards refills you when you've emptied out. That first ability is the design story. Discarding your hand is a real cost early, but on an empty grip it's pure card advantage priced as a loyalty gain rather than mana, and the "play them this turn" clause turns her into an impulse-draw engine that punishes decks trying to grind a red aggro-midrange shell into topdeck mode. The ultimate is almost incidental: search your graveyard and library for red instants and sorceries, cast them, and add six red mana to power the whole chain, a payoff for a deck already built on cheap spells rather than a reason to build one. What makes her coherent is that all three abilities point the same direction. There's no defensive minus, no fog, no bounce. She protects herself the only way a burn walker honestly can, by ending the game before the loyalty runs out, and every mode is a variation on turning cards into damage and damage into more cards.
