Professor Trelawny

{1}{u}: Flip a coin. If you win the flip, look at
the top card of your library. If it is a sorcery, draw a card.
At the beginning of each end step, flip three coins. For each one you win, scry X, where
X is a sixth of the number of cards in your library, rounded up.
You may cast sorceries as though they had flash.
