Whenever an opponent casts a creature spell,
untap Aedonz unless that player pays {1}.
{1}{u}, {t}: Tap target creature. That creature
loses all abilities and doesn't untap during its
controller's next untap step.
{1}{u}{u}, {t}: Exile target spell or activated ability.
Aedonz doesn't untap during its controller's
next untap step.
