Encrypting Wand

At the beginning of your upkeep, put a charge
counter on Encrypting Wand. Then you may
exile an instant or sorcery card from your hand
with converted mana cost equal to or less than
the number of charge counters on Encrypting
Wand.
{t}: You may cast an instant or sorcery card exiled
with Encrypting Wand without paying its mana
cost.
