Mazus, Grand Magus

When Mazus, Grand Magus enters the
battlefield, reveal the top seven cards of your
library. Put all cards with Spellcraft abilities
from among them into your hand and the
rest on the bottom of your library in any order.
Creatures you control with Spellcraft get +1/+0.
Many hate Mazus for his harsh mentoring.
Those who leave regret they didn't stay.
