The Theorist, Jace Beleren

Oracle text

At the beginning of each opponent's draw step, you draw a card. +1: Create a 1/1 blue Illusion creature token. −2: For each opponent, return up to one target artifact or creature that player controls to its owner's hand. −6: Draw three cards. Then put X +1/+1 counters on each creature you control, where X is the number of cards in your hand.
