Flares of Duality

The first instant or sorcery spell you cast each
turn costs {2} less to cast.
If an instant or sorcery spell you own would deal
damage to a permanent or player, it deals that
much damage plus 2 to that permanent or player instead.
If an instant or sorcery spell you own would have
you draw one or more cards, you draw that many
plus an additional card instead.
