Sorcery, 4{B/R} (5)
Uncommon
Return up to one target creature card from your graveyard to the battlefield if {B} was spent to cast Torrent of Souls. Creatures target player controls get +2/+0 and gain haste until end of turn if {R} was spent to cast Torrent of Souls. (Do both if {B}{R} was spent.)

5/1/2008: The spell checks on resolution to see if any mana of the stated colors was spent to pay its cost. If so, it doesn't matter how much mana of that color was spent.
5/1/2008: If the spell is copied, the copy will never have had mana of the stated color paid for it, no matter what colors were spent on the original spell.
5/1/2008: When you cast the spell, you choose its targets before you pay for it.
5/1/2008: The effects of the spell happen in order. If you spent both {B} and {R} to cast Torrent of Souls, first you'll return a creature card from your graveyard to the battlefield, then all creatures you control -- including the one you just returned -- will get +2/+0 and gain haste until end of turn.
