Genocide

Choose Creature type, Target player exiles all creatures on the battlefield with that type,
exiles all others from their hand and library.
Overload {w}{u}{b}{r}{g}{2}{p/b}{p/c}{p/g}{p/r}
Replace 'Target Player' with 'Each Player'.
"You have to understand what caused genocide to
happen, or it will happen again."
