Well, yeah, that's true. There are some pre-evos who simply have "different stats" rather than "worse stats" than their full evos, thus favouring different sets and such, like Porygon2/ Porygon-Z etc. But what I really meant was more like: no pre-evolution is far superior or more powerful than any of the legal full evos, basically. None of the pre-evos are uber material or anything close to that.
Oh, and if you wanna battle despite not being in the tourney, just send me a PM whenever we're both online. (though right now, I gotta log off for the time being).
