D Rank:
Reserved for Pokemon who have a small niche in the current UU metagame, but have very noticable flaws that make them more trouble then their worth the majority of the time.
omg found the ultimate typo
Anyways, I wouldn't have pointed this out if there wasn't anything bugging me about it - How come is even in D rank? What are their current niches in the UU metagame? Shedinja dies to many things, considering sandstorm damage (Hippowdown), hail damage (Mega Abomasnow), stealth rocks (also Hippowdown), toxic (EVERYTHING), and 5 different move typings (Sucker Punch...). It does have base 90 Attack and access to Swords Dance, but still. I understand D Rank is supposed to mean that they're near useless in whatever tier they're in, but I feel Shedinja just shouldn't have a rank at all. I predict Shedinja to be going further down in the tiers.
Here's a complete list of pokemon Shedinja does well against, and what he doesn't:
PRELIMINARY XY UU Ranking tier list V.1
S Rank:
Reserved for Pokemon who can sweep or wall significant portions of the metagame with little support, and Pokemon who can support other Pokemon with very little opportunity cost ("free turns"). Also the home of Pokemon who can easily perform multiple roles effectively, increasing their versatility and unpredictability. If the Pokemon in this rank have any flaws, those flaws are thoroughly mitigated by their substantial strengths.
(Flamethrower)
(Any move, since it learns anything)
(AV with Fire blast)
(Shedinja Walls)
A Rank:
Reserved for Pokemon who can sweep or wall significant portions of the metagame, but require some support or have some flaws that prevents them from doing this consistently. Supporting Pokemon in this rank may give opponents free turns or cannot create free turns easily themselves, but can still do their job most of the time.

B Rank:
Reserved for Pokemon who cannot sweep through or wall significant portions of the metagame, but can properly fulfill a given offensive/defensive niche. Support Pokemon in this category have flaws that prevent them from doing their job or are setup bait for dangerous sweepers. Pokemon who are partially outperformed by a Pokemon in A or S Rank, but are otherwise very dangerous, may also fall into this category.

As unnecessary as this was, I had to prove Shedinja shouldn't even get a mention in UU. Shedinja walls 33 pokemon on this list potentially, but otherwise should not have a mention.
