The Wise Wizard

When The Wise Wizard enters the battlefield,
look at the top six cards of your library. You may
put any number of instant and sorcery cards
from there into your graveyard. Put the rest on
the bottom of your library in any order.
Incantation — Whenever you cast your second
instant or sorcery spell each turn, return target instant or sorcery card from your graveyard to
your hand.
