Knollspine Dragon

The seven-mana refuel that converts a burn deck's entire offensive line into a fresh grip. The trigger keys off damage dealt to a single opponent this turn, so the dragon rewards a turn already spent pointing reach and direct damage at a face: every bolt, every attack, every shock becomes a card. Discarding your hand first is the price, but for a board that has already dumped its grip throwing burn, that discard costs nothing and the draw is pure profit. The dynamic inverts the usual tension of a flying finisher. A 7/5 body is its own clock, the kind of creature that ends games in two swings, so most dragons force a choice between racing and grinding. This one collapses the choice: the same turn that delivers a lethal-looking aerial threat also restocks the resources to close out if it doesn't land. The window is what makes it work. The draw happens on entry, counting damage dealt earlier in the turn rather than damage the dragon itself deals, which front-loads the payoff onto aggression already committed instead of promising it on a future attack. Cast it dead and you draw nothing; cast it as the capstone on a turn that has already bloodied the opponent, and it hands you the second wind to finish the job.
