Ashling, Flame Dancer (Modern Horizons 3)

You don't lose unspent red mana as steps and phases end. Magecraft — Whenever you cast or copy an instant or sorcery spell, discard a card, then draw a card. If this is the second time this ability has resolved this turn, Ashling deals 2 damage to each opponent and each creature they control. If it's the third time, add {R}{R}{R}{R}.
