Blessing of Frost

Because Blessing of Frost doesn’t target any creatures, you determine how the +1/+1 counters will be distributed as Blessing of Frost resolves. Players may respond to Blessing of Frost as normal, and they’ll know how much snow mana you spent to cast it, but they won’t necessarily know how the counters will be distributed.

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 {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.

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.

If you cast Blessing of Frost without spending snow mana, no +1/+1 counters will be distributed. You may still draw cards if your creatures are large enough.

If Blessing of Frost is copied, no mana was spent to cast the copy, so no +1/+1 counters will be distributed. You may still draw cards if your creatures are large enough.
