I can give you some stuff to take out in the final paragraph if you'd like:
Cut the second incredible in the first sentence.
Maybe just cut the whole 'absence of Sand Veil'? That's not really much of a shortcoming IMO, more of a 'thing that is banned/made him banworthy'. Yes, he used to have it, but given as no non-uber has that NOW, it's not exactly a shortcoming.
As long as nothing relevant has 102 Speed, is it really necessary to mention the uniqueness?
Also, resisting SR doesn't give him switch-in opportunities so much as it gives him freer switch-ins. If Mence could switch in and do whatever Chomp was about to do, he'd probably do it.
Oh yeah and finally:Chomp is versatile as hell, as you yourself have noted. So his analysis might be a little longer, because there's more to cover.
(Also, provide him, not provides him, in the first paragraph.)
Maybe cut out mentions of BW move tutors and generation shift? I've seen such mentions before and allowed in, but it's just kind of taking up space. (Sub-typing? Just typing?)
Does Chomp even restalk phaze? Never really seen that.
