Ice Queen La Saia

Ward — Put an ice counter on target land you control.

Creatures and lands you control are snow in addition to
their other types. The same is true for creature spells you
control, and creature and land cards you own that aren't
on the battlefield.

{s}{s},{t}: Tap target creature and put an ice counter on it.

Permanents with ice counters on them don’t untap during
their controllers’ untap steps.
