Firebending 2 (Whenever this creature attacks, add . This mana lasts until end of combat.)
Whenever you cast a spell while Fire Lord Azula is attacking, copy that spell. You may choose new targets for the copy. (A copy of a permanent spell becomes a token.)
Swing with Azula every turn to generate via Firebending, then chain spells during your combat to copy each one for free value. You build a Grixis spellslinger/storm-lite shell that turns one removal spell, burn spell, or extra-turn spell into two, snowballing card advantage and damage until you burn the table out or take infinite turns.
Add ramp and rituals (Dockside Extortionist, Jeska's Will) to cast multiple spells per combat and fuel X-spells. Prioritize evasion and protection (Whispersilk Cloak, Swiftfoot Boots, Rogue's Passage) so her trigger reliably fires, then lean into extra-turn and free-cast spells (Time Warp effects, Mizzix's Mastery) to convert a single combat into a lethal storm. Tighten the manabase with fast lands, fetches, and signets to support the demanding Grixis curve.
