Daede, Banished of Farrum

Skulk, lifelink

Whenever you gain life for the first time each turn, Daede, Banished of Farrum connives.

Whenever you discard one or more cards, you may
exile one of them with mana value less than or equal
to Daede’s power from your graveyard. If you do,
you lose life equal to its mana value. Until end of turn, you may cast that card without paying its
mana cost.
