I love that Chesnaught's got the whole Knight's theme going for him and Greninja looks pretty darn cool but I agree with you on Fenniken. I love its typing and the fact that it's based on a Mage/ Witch but I was expecting Delphox to look a little more enchanting or bewitching instead of how lackluster it actually is.
Drought boost + Special Attack bonus (Mega Evolution) + STAB + already high Special Attack Stat = ONE VERY OP FLAMETHROWER. Drought Solarbeam takes care of Rock and Water types too so I'd call it a win for Mega Charizard Y. Mega Charizard X is in perpetual shiny mode and its part Dragon Type. I think I could get better use out of its Y version but I'd be lying if I said that I didn't love the fan-service. Mega Venusaur gets a heck of a lot more bulk added with resistance to 2 of its major weaknesses so it just gets better. Mega Blastoise I'm a little disappointed with. Like you said, it looks insanely cool but I just feel that it could have been better with a Water/ Steel typing.
I love Chepsin's and Froakie's is okay, but the heck is up with Fennekin's? That thing looks kind of awful. :( As for the Kanto ones, Charizard's black/blue mega is cool and Blastoise's mega is insanely cool but the rest are kinda lame. Do you like them?
To sum it up, my University's Administration fail completely at organization. I had to go back and forth trying to get them to sort out my grades on the system and it was a pain to deal with. Things are sorted out now so I'm good.
No problem. I can sympathize. University can drain you, but you make the sacrifices for a greater purpose. Hope you get through it one piece.
