Tyrion Lannister, the Imp

At the beginning of your upkeep, if an opponent has more cards in hand than you, draw cards equal to the difference.
Noncreature spells you cast cost X less to cast, where X is the difference between the number of cards in your hand and the greatest number of cards in hand among all players.
Whenever a creature you control deals combat damage to an opponent, that player draws a card.
