Obscura Ascendancy | Enchantment | | Whenever you cast a spell, if its mana value is equal to 1 plus the number of soul counters on Obscura Ascendancy, put a soul counter on Obscura Ascendancy, then create a 2/2 white Spirit creature token with flying. As long as there are five or more soul counters on Obscura Ascendancy, Spirits you control get +3/+3. | Igor Krstic

Brokers Ascendancy | Enchantment | | At the beginning of your end step, put a +1/+1 counter on each creature you control and a loyalty counter on each planeswalker you control. | Dallas Williams

Maestros Ascendancy | Enchantment | | Once during each of your turns, you may cast an instant or sorcery spell from your graveyard by sacrificing a creature in addition to paying its other costs. If a spell cast this way would be put into your graveyard, exile it instead. | Jodie Muir
