Aleza, The Witch of Winter

At the beginning of your upkeep, exile the top card
of your library. If it’s an instant or sorcery, you may cast it this turn without paying its mana cost. If you don’t cast it, Eleza deals 2 damage to any target.

At the beginning of your upkeep, if two or more noncreature spells were cast, transform Aleza, The Witch of Winter. 5/5>
