Gallack, the icy Shrieker

Snow Permanents you cast are Cold-blooded
(For each colored Mana in their Manacosts you
may pay {s} instead)
{w}{u}{b}{r}{g}: Put an ice counter on up to three
target permanents.
If an permanent you don't control with an ice
counter on it becomes tapped, that permanent
doesn't untap during its controller's next
untap step.
