Malrok, Warden of Sedraxis

Whenever you cast a spell, if you discarded one
or more cards, payed life, or sacrificed one or
more permanents as an additional cost to cast
the spell, create a 3/1 Black Skeleton creature
token with haste.
{u}{b}{r}, {t}: Target noncreature spell in your
graveyard gains flashback, where the flashback
cost is its converted mana cost plus discarding
a card.
