Subjugation (Spells your opponents control with
a lower mana cost cannot be played immediately
after this.)
Blue and red spells you control cost {1} less to
cast. Blue and red spells your opponents control
cost {1} more to cast.
If a permanent you control has both {u} and {r} in its mana cost, it has protection from
blue and red.
