Last Charge of the Light

Cast this spell only if you control only white or red creatures.
Creatures you control gain haste and first strike and get +5/+0 until end of turn. White creatures you control gain lifelink and get +0/+3 until end of turn. Red creatures you control gain menace and get +0/+2 until end of turn.
And so the last forces of light charged in a final pursuit for all that was right with the world: Hope, love, the freedom to live.
