Astralmancer

Shadow
When Astralmancer enters play, create 2
colorless Trap artifact tokens with "Sacrifice this
card: If target permanent would be exiled or
phase out this turn, tap it instead. It deals
damage equal to its converted mana cost to any
target," and "Sacrifice this card: If target spell
would be exiled this turn, put it into either the
graveyard or hand instead. It deals damage equal
to its converted mana cost to any target."
