For each {b} or {r} in a noncreature spell cost, you may pay
2 life rather than pay that mana.

Pact for Power — If an instant or sorcery spell you control would deal damage, it deals that much damage plus the amount of life you have paid casting noncreature spells this turn.

Thirst for Knowledge — Whenever you discard a card, you may pay 2 life, if you do, draw a card.
