Welcome to Smogon,
INSANE CARZY GUY, but there is one thing I need to nitpick about. No Pokemon in this game should be using Struggle Bug, as there is no Technician mon with a decent SpA stat that needs a Bug move. Shedinja only has 1 HP anyway, so inflicting a stat drop at most helps you if somebody else needs to get in, which is not enough to justify a 50 BP move off 45 SpA. Just use X-Scissor and break through stuff.
Protect-stalling, if you can pull it off, is somewhat viable.
Onto my opinion about Sheddy: To think that, following a proposal to blacklist it, there would actually be serious discussion. I'm not sure how to feel about it. It's been something I feel a lot of people have simply dismissed offhand as a low-ladder gimmick, but at the same time
virgin was kind enough to grace us with a replay in which Sheddy actually puts in work, and to actually
use Wonder Guard instead of simply abusing it. It's kinda like Protect: used well, it can kill momentum, but abused, it simply makes you predictable. I also think virgin captures the essence of Sheddy perfectly in one sentence from his initial nom (brackets are my own input):

On his own, he doesn't do much damage [especially from base 90 in a game where he can't afford to Swords Dance], but the very threat of Shedinja on the team forces your opponents to play differently.
All the same, there's no denying the support it needs to stay in, since no matter which item you run you still need to keep
a lot off the field in order for Sheddy to get in. I think some people see Wonder Guard as a free opportunity to get in and sweep, when in reality it works a lot better as a pivot, absorbing crucial hits and then bouncing out before it has to take a hit. Baton Pass means it's not the end of the world should it take a Toxic or Will-O, as provided it takes it the turn it's passing out, a cleric can save Sheddy's life.
All said, we all know that Shedinja requires a
ton of support to function properly, but it can also provide some support. This allows it to, in my opinion, function on certain teams, and thus worthy of a ranking, but I would say it deserves
E rank if and when that is implemented, as it remains the frailest Pokemon in the entire game, and the degree of required support may be judged to be too much by some--in fact, many--people.
