Azula, On the Hunt (TLA)

Legendary Creature — Human Noble

Firebending 2 (Whenever this creature attacks, add {R}{R}. This mana lasts until end of combat.) Whenever Azula attacks, you lose 1 life and create a Clue token. (It's an artifact with "{2}, Sacrifice this token: Draw a card.")

Reliable card advantage engine for Rakdos and Grixis midrange decks. Azula generates mana and Clues on every attack, turning combat into a consistent draw engine while the life loss is easily managed in decks that can leverage the red mana for threats or interaction. The repeatable value makes her a solid threat in Pioneer and Modern midrange shells, though she requires a reasonable clock to justify the setup cost and life total investment.
