Aisha, Dark Magician

As long as this creature is in play, noncreature
and nonartifact spells you cast have Storm.(When you cast that spell, copy it for each spell cast before it this turn. You may choose new targets for the copies.)
If {b} was paid for this creature's casting cost, it
has Wither. (This deals damage to creatures in the form of -1/-1 counters.)
"You can't handle this!"
