It is everywhere and nowhere, a place unbound by logic, just beyond the real.

Kaldheim

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.

Although Faceless Haven will have all creature types after its last activated ability resolves, it will not have the changeling keyword ability.

If Faceless Haven becomes a creature but hasn't been under your control since the beginning of your most recent turn, it can't attack or be tapped for mana.

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 {S} using mana that wasn't produced by a snow source.

Some cards have additional effects for each {S} spent to cast them. You can cast these spells even if you don't spend any snow mana to cast them; their additional effects simply won't do anything.

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

The {S} symbol is a generic mana symbol. It represents a cost that can be paid by one mana that was produced by a snow source. That mana can be any color or colorless.
