Not really, did you expect Turtwig to do better against Hippowndon, Claydol, Drapion then Torterra? its not an exception, the writers just messed up and didnt give it a win because they were to worried giving 300 wins to Infernape.
He evolved twice due to lack of power, I doubt Turtwig could do better, in fact he couldn't because if he was still a Turwig the battle were set anyway, he would have lost those.
Nah, Gible shouldn't be a punching bag.
Today or this week?
No the thread has been up for two weeks or so, even before we saw the random Palpitoad in this week episode.
People on serebii use 'powerhouse' way too much. I like Palpitoad, would like to see it become a Seismitoad though. I don't view his Unova team as any stronger or weaker than any of his other teams. They share a lot of similarities (grass starter, flying type, etc). I've never been one for ALL of his Pokemon evolving, but I look at Oshawott, Snivy and Scraggy and can't help but want more. Also think they might miss the boat on an interesting 'trade story' in which Boldore becomes Gigalith, maybe gets separated from Ash for a while, whilst Ash gains possession of another Pokemon that evolves via trade, before being reunited.
