MAGIC: THE GATHERING
When Aria of Flame enters the battlefield, each opponent gains 10 life.
Whenever you cast an instant or sorcery spell, put a verse counter on Aria of Flame, then it deals damage equal to the number of verse counters on it to target player or planeswalkers.
Since the release of Modern Horizons, Aria of Flame has seen play in Izzet Phoenix and Storm decks. You won't mind if your opponent gains ten life when you can deal exponential damage to them!
