Ghetsis' Hydrogeion ripped my team to shreds. The battle against him was the only one that I had to restart, except for maybe the second gym battle. I decided to teach Brick Break to a couple of Pokémon after getting ripped to shreds in the first match, but it didn't help at all, since they got 1-hit-KOed before they could attack. I beat him the second try with mostly luck. The gym leaders and Elite 4 were the easiest to beat of any game I've played. I 1-hit-KOed through a couple of them, I think Skyla and Iris, using Zebstrika and Haxorus. I used Archeops against Iris' Druddigon, since Haxorus was having trouble dealing with the ones before hers. I also used Archeops to 1-hit-KO through Marshal's team. Caitlin gave me a lot of trouble, however. N wasn't that hard for me to beat, especially compared to the trouble Ghetsis gave me.
