Azula, Cunning Usurper

Theft-and-recast cards usually reach into one zone; this one reaches into two, and the second is the crueler half. The enters trigger forces an opponent to exile a nontoken creature they control and a nonland card from their graveyard, then hands you a window to cast either. The graveyard clause is what separates this from ordinary reanimation-in-reverse: it does not just deny the opponent a body on board, it strips a flashback target, a recursion payoff, a delve fuel pile, whatever they were banking on getting back, and it puts those cards on your side of the table instead. What you steal, you can cast on your own turn as though it had flash, with mana of any type, so the stolen creature and the stolen spell both fold into your fair-mana plan without color friction. Firebending 2 exists to underwrite exactly that: the attack trigger adds two red the moment she swings, whether or not she gets through, and the color-agnostic recast clause turns that red into castable fuel for whatever you lifted, so the aggressive line and the value line are the same line. The tension the design resolves is that theft effects in blue-black usually cost you tempo to set up; here the recast permission is instant-speed on your turn only, tight enough to reward a proactive board rather than a reactive holding pattern. At five mana she is a midrange threat that wins the exchange the instant she lands and keeps generating fuel every time she declares an attack.
