Don't worry about it; you actually gave me a great idea here. Before my giveaway, I'm going to see which Pokémon families are NOT in W2 anywhere and trade those ones in my box over to there. That takes care of future Pokédex concerns, though I did promise myself I wouldn't use them in the storyline battles themselves (only training in the wild), and I will see if I can stick to that promise. Rhyhorn sitting at Lv.22 ATM and no Trainer fighting, and now Treecko and one of my Charmanders can join it. :D
