Professor Jacquel

Whenever you cast a non-creature spell,
investigate. (Create a colorless Clue artifact token
with "{2}, Sacrifice this artifact: Draw a card.")
Whenever you sacrifice a clue, put a +1/+1
counter on Professor Jacquell.
Whenever one or more +1/+1 counters are
placed on Professor Jacquell, if it has three or
more +1/+1 counters on it, transform.
