Current version can be seen here. Prior to Beta 3.4, Snow Storm cost 7 and caused both players to draw cards until they had 6 each in their hands. This was to help with the previous ability of Patience which was to deal 30 damage to the opponent once they tried to draw cards from an empty deck. However with the change in the soul type's ability during Beta 2.9 to paralysing all enemies on their first turn, Snow Storm was reworked to transform every monster on the board into Ice. After Beta 5.7 its cost was increased to 8g from 5as it was very widely used and able to change the game situation frequently, making it incredibly hard to beat when used correctly in combination with other cards.
