Archmage of Runes | Creature | Giant Wizard | Instant and sorcery spells you cast cost {1} less to cast.
Whenever you cast an instant or sorcery spell, draw a card. | Kai Carpenter
Consuming Aberration | Creature | Horror | Consuming Aberration's power and toughness are each equal to the number of cards in your opponents' graveyards.
Whenever you cast a spell, each opponent reveals cards from the top of their library until they reveal a land card, then puts those cards into their graveyard. | Karl Kopinski
