If you do not have any snow cards in your deck, you must resolve the “suffer 2 damage” action.
If you choose this action, you discard the “Snowfall” card and reveal the next snow card from your deck. You must resolve this card as normal.
Another player can help you with the “Snowfall” card to reveal a snow card from their deck. If another player helps you with the “Snowfall” card, you can continue to help them with the next snow card .
