10 rulings from Wizards of the Coast
- 5 February 2021If Blood on the Snow is copied, no mana was spent to cast the copy, so you can return only a creature or planeswalker card with mana value 0.
- 5 February 2021You choose a mode for Blood on the Snow as you cast it. The last part of the effect (returning a card to the battlefield) happens no matter which mode you choose.
- 5 February 2021If you cast Blood on the Snow without spending snow mana, you can return only a creature or planeswalker card with mana value 0. (Planeswalker cards with mana value 0 likely not coming soon.)
- 5 February 2021Snow is a supertype, not a card type. It has no rules meaning or function by itself, but spells and abilities may refer to it.
- 5 February 2021The {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.
- 5 February 2021Snow 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.
- 5 February 2021Blood on the Snow doesn’t target any creature or planeswalker card in your graveyard. You choose which one to return to the battlefield, if any, as Blood on the Snow resolves. Notably, you could return one of the creatures or planeswalkers that was just destroyed by Blood on the Snow.
- 5 February 2021The 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.
- 5 February 2021Some 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.
- 5 February 2021If a card in a graveyard has {X} in its mana cost, X is considered to be 0.
