Jace Beleren

{u}, {t}: Choose a card that hasn't been chosen
from Jace Beleren's spellbook. Create a copy of
the card with the chosen name. You may cast the
copy. (Jace Beleren's spellbook contains Contentious
Plan, Control Magic, Dispel, Jace's Phantasm,
Hover Barrier, Narcomoeba, and Unsubstantiate.
You still pay its costs. A copy of a permanent spell
becomes a token.)
