I started with Swampert as my mega, using Blastoise for X/Y challengers, but it turns out that Swampert is not great on a mono-water team. Everyone's bringing grass type moves and pretty much any grass move will OHKO Mega-Swampert. So Blastoise took over and did much better. You might notice that Walrein and Ludicolo have practically the same set, that's because Friday night I bred Ludicolo to replace Walrein, since I kept getting destroyed by Mow and Wash Rotoms. Ludicolo did much better. Not sure why I didn't use him to start with.
