Chandra, the Firebrand

The middle ability defines this Chandra entirely: a planeswalker that copies your next instant or sorcery turns her into a value engine wrapped around a single tick of loyalty. The math is straightforward and seductive. Spend the minus-two, then cast a burn spell, a draw spell, a tutor, anything that same turn, and get two for the price of one, with the freedom to redirect the copy. It is Fork or Reverberate stapled to a permanent that survives to do it again, and the design tension she resolves is how you make spell-doubling repeatable without breaking it: you pay in loyalty, and the trigger only catches a spell cast the same turn you activate it. There is no banking the doubler for later; the window closes when your turn ends, so you commit to the payoff now or you waste the minus-two entirely. The plus-one is deliberately small, a single point of damage that exists mostly to keep her alive and chip at planeswalkers or one-toughness creatures rather than to dominate a board. The ultimate is the splashy finish, six damage to each of up to six separate targets, but it is rarely the point; she is built to be ticked down to the copy almost immediately. Among the early walkers of her line she is the cheapest and most modest, a four-mana walker whose ceiling is dictated entirely by the quality of the spell you copy off her. Empty the hand and she is filler; build around the doubling and she rewrites a turn.
