I think that Samurott's only real problem (aside from not having access to Shell Smash) is that they didn't do a real good job showing it off.
We know that it can at times be bipedal to dual-wield those shellblades, but in games it's stuck in that stiff looking pose. I don't play the tcg so maybe there is some good art out there???
And the Unova anime was the worst. You got shit like this
