Eri's Spellbook

{u/r}{u/r}{u/r},{t}: Search your library for a blue or
red spell that has a mana value of {4} or less and
place it into your hand.
{u/r}{u/b}{b/r},{t}: Search your library or graveyard for a
blue, red or black spell that has a mana value of {6} or less and place it into your hand. If you
chose a spell from your graveyard, place a stun
counter on Eri's Spellbook and exile the spell the
next time it is cast.
