Elgyem

Straight out of Area 51 or some thriller alien movie, you'd better pray that this little green man comes in peace; with base 85 Special Attack and Analytic boosting its attacks, Elgyem isn't something you want to get on the bad side of. Normally such a low Speed stat on an offensive Pokemon would be awful, but Elgyem somehow manages to make it work through the use of Analytic, above average 55 / 55 / 55 defenses, and Recover. Its Psychic typing even manages to make itself useful, giving Elgyem a nice resistance to Fighting-type attacks that allows it to switch in on most Fighting-types without much worry. Analytic really is what makes Elgyem so impressive though; its Speed is so low that it will almost always be slower than its opponent, so Elgyem consistently has the equivalent of a free Life Orb boost without the added recoil. Because of the sheer power that Analytic provides, Elgyem is easily the best bulky attacking Psychic-type in LC and one of the best bulky attackers in the tier.

Although Elgyem might have superior technology, impressive firepower, and adorable looks (it even has a little tail!), it's not without flaws. Once Elgyem has taken down a Pokemon, it's usually in range to be revenge killed. This issue is further compounded by Elgyem's weakness to two of the best offensive Pokemon in LC: Pawniard and Misdreavus. Even though Elgyem can actually survive their attacks at full health, it will almost always have taken a hit or two before KOing a Pokemon and thus will very rarely be at full health against these three. Elgyem also takes quite a bit of skill to use effectively. The opponent will often switch out against Elgyem, and it can take good prediction to nail whatever is coming in... unless you can get Elgyem's mind probing devices working, that is.
