Teacher of Humility

Infiltrate -- Each opponent creates a 0/1 white
Overseer creature token that can't block with
"Whenever you draw a card except for the first
one you draw each turn, reveal that card. Cards revealed this way cost {2} more to cast." (Triggers
the first time this hits an enemy player.)

Whenever Teacher of Humility deals combat
damage to an opponent, each player draws a card.
