Pilfering Hawk

Snow is a supertype, not a card type. It has no rules meaning or function by itself, but spells and abilities may refer to it.

Snow isn’t a type of mana. If an effect says you may spend mana as though it were any type, you can’t pay for snow mana using mana that wasn’t produced by a snow source.

The Kaldheim set doesn’t have any cards with mana costs that include snow mana , but some previous sets do. If an effect says such a spell costs 1 generic mana less to cast, that reduction doesn’t apply to any snow mana costs. This is also true for activated abilities that include snow mana in their activation costs and effects that reduce those costs.
