Xazzos, Chaos Commander

Haste
{1}{b}{r}, {t}, Sacrifice Xazzos, Chaos Commander:
Two target players each switch battlefields,
hands, libraries, graveyards, and command
zones. (They essentially just switch spots.)
You may pay two life rather than pay for a
colorless mana in Xazzos, Chaos Commander's
mana cost. This effect can not reduce the
amount of colored mana you pay.
