Akara Tor, the Attentive

Whenever you cast a spell during an opponent's
turn, you may pay {1}. If you do, draw a card.
{1}{w/u}: The next sorcery spell you cast this turn
may be cast as though it has flash.
{b}{r/g}: Draw two cards. You lose 2 life. You may
activate this ability only if an opponent has drawn
three or more cards this turn, and only once each
turn.
