I'm looking to add a Spheal/Walrein to my team in Black 2. However, It is Spring in my game, and Winter won't occur until August.
However, I do have two 3DSs, allowing me to trade between my White and Black 2 games. If possible, I'd want to catch Spheal before winter in the latter game, without trading. Is there any way for me to catch it now, or should I just trade between games?
