Blizzard Brawl is too powerful for its mana cost vs. other cards.
Rabid Bite and other forced fight cards cost 2 mana, and typically give no bonuses.
Blizzard brawl gives a +1 bonus, AND also makes the creature indestructible? That is ridiculously overpowered. It has a fake BS limitation of '3 snow permanents', but that will be met just by snow lands pretty much every single time its cast, so it isn't a limitation.

Suggest removing this card, or at the very least increasing mana cost to 2 like every other forced fight card and removing the nonsense indestructible bonus.
