The Professor

Whenever you Learn, put a Grade counter on the Professor. Merfolk creatures you control have “Whenever this creature deals combat damage to an opponent,
learn.”
Whenever you search your library, double the number of Grade counters on the Professor.
Merfolk you control get +X/+0 for each Grade counter on the Professor.
The Professor’s power is equal to the numerical grade on the standard ten point scale your deck box received minus your age, divided by ten.
