{3}{p/w}{p/b} Madness- (Sorcery) Each player puts a
Traitor counter on a creature they control and sacrifices the rest. Each of those creatures can't
attack you or planeswalkers you control for as
long as it has a Traitor counter on it.
Canvas- Non-Aberration creatures can't attack you
or any Planeswalkers you control unless their
controller pays {p/c}{p/c}{p/c} for each creature.
