Hey Pinkacross! Heard that you were talking about hail/snow. Moves and abilities like blizzard/slush rush act the same in both weathers. Hail does damage, while snow increases the defense stat by 50%. Funnily, Eiscue's Ice Face ability is restored in both weathers. This makes for a pretty mean stall strategy to stop most physical attackers.
On that note, here's a team for you to try out.
