Honestly guys, Sharpedo didn't have that significant of an impact. It wasn't used a notable amount even for the majority of the time is was in RU, it only spiked near the end of its tenure. Looking at the remaining mons I kept debating over Druddigon, for its continuous rise and impact since BW2 and Sceptile for its omnipresent, and eventually decided on Sceptile as my vote. Really I'd be happy with either of those two in #10 though. Though I'd probably put Uxie over each of them.
