Just started my copy of Black 2. Going to be playing mainly with Tepig evo line/Sunkern/Azurill from Flocessy Ranch and then Dunsparce. I will likely add N's Zorua and then anything which takes my fancy in the last slot. I'll probably update this post or write another depending on how well it goes, I'm in Cheren's Gym at the moment so I can't really comment on much. So far Sunkern hasn't been great, but we will see.
