Elnora Fablescroll

Whenever another player casts an instant or
sorcery spell, exile it as it resolves.
You may cast spells exiled with Elnora
Fablescroll. If you do, you may spend mana as
though it were mana of any color to cast those
spells.
Whenever you cast an instant or sorcery spell
from anywhere other than your hand, draw a
card.
