Ashling, Flame Dancer

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}.
