White Chain, Disembodied

Devoid (This card has no color.)
Whenever you cast an instant spell during your
main phase, draw a card, then discard a card.
This ability triggers only once each phase.
Whenever you cast a sorcery spell, if it isn't your
main phase, draw four cards, then discard three
cards. This ability triggers only once each turn
cycle. (If it triggers on an opponent's turn, it can't
trigger again until that player's next turn.)
