Companion — Your starting deck contains only cards with odd mana values and land cards. If a source you control with an odd mana value would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.
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.
Choose one — • Return target multicolored permanent card with mana value 3 or less from your graveyard to the battlefield tapped. • Counter target instant or sorcery spell. • Destroy target creature or planeswalker with mana value 3 or less.
