Phox Flare, Flameberge Mage

Each time you deal damage with an instant
or sorcery, you deal an additional 1 damage to a
random opponent or opponent's creature.
{1}{u}{u}, {t}: Draw cards equal to the amount
of mana you spent on instants and sorceries this
turn. This doesn't include the mana spent on
generic mana, colorless mana, or colored
Phyrexian mana paid with life instead of mana.
