Absol, by far in usage. I almost clean OHKO swept 2 E4 people with 2 Swords Dance + Slash. Holy balls. Imagine if this thing had a better moveset and got an evo line, him plotting in the middle. OU for sure, considering its UU right now (from last time I checked)
I like Sceptile the best because he was my second starter ever, in Ruby. My first starter, quite frankly, is very obvious.
What Kalos starter was I going to choose before I got X? Froakie. But then I absolutely fell in love with Chespin's design and Chestnaught and I could not resist not using him so I had to choose him, last minute. I was team froakie until I was in gamestop. Then it all changed.
