Belanor, God of Winter

Indestructible, frost touch (Whenever this creature
deals combat damage to a creature, tap that creature.
It doesn't untap during its controller's next untap step.)
As long as your devotion to snow is less than
three, Belanor isn't a creature. (Each {s} in the activation costs of permanents you control counts
toward your devotion to snow.)
{2}{s}: Target creature gains frost touch until
end of turn.
