I have 104 pages just for the basic card dex binder. That includes official alternate types and Mega Pokemon. Unofficial ones like water Lugia and fighting Torkoal are not in there...at least not yet. I've debated adding those too. I pushed a step further and made everything holo/reverse holo if it can be. So far the only exceptions are water Surskit, fairy Granbull, colorless Ho-oh, and fighting Omanyte/Omastar.
I would suggest a page spacing between each generation. That way when you add cards, and trust me you will be doing this after most sets release, you're only moving one generations worth in space rather than up to six. You can imagine how fun it was to get Primal Clash Tentacool/Tentacruel would be if the gens weren't seperated.
Sometimes I change my cards too. I want the grass Ludicolo from Primal Clash for it, right now it's the Platinum one I have.
