Professor Binns

When Professor Binns enters, return target historic card with mana value 3 or less from your graveyard to your hand.
Whenever you cast your first historic spell each turn, tap up to one target creature. (Artifacts, legendaries, and Sagas are historic.)

Professor Binns opened his notes and began to read in
a flat drone until nearly everyone in the class was in a deep stupor, occasionally coming to long enough to copy down a date, then falling asleep again.
