Since everyone is talking about Dark types I want to throw out this fun core. It's not like anyone has had notable success with Zoroark, but this core is pretty fun to use and the introduction of Sludge Bomb to Zoroark's movepool over the summer has made Zoroark usable in OU, mainly because he isn't a free switch in to Clefable anymore. Mega Lopunny forces a lot of switches between Fake Out and her blazing speed stat, and this compliments Zoroark's Illusion perfectly. Dark Pulse hits all of Lopunny's counters for huge damage, paving the way for Lop to clean.

Zoroark's EVs let him outspeed Jolly Garchomp since running 252 speed ties with base Manectric and Mega Pinsir, who aren't really worth the effort. 80 atk EVs guarantees the OHKO on Latios w/ Sucker Punch. The rest is dumped into SpAtk to hit as hard as possible. I prefer Dark Pulse over Night Daze because the 20% flinch rate comes into play more than the accuracy drop from ND, considering your opponent is still has pretty good accuracy after one drop, but it's up to you since Night Daze has 5 extra power. You can run a full special set with flamethrower and focus blast for more power, but Zoroark really misses having Sucker Punch.
Ice Punch is slashed because Zoroark has trouble breaking through Hippo and Chomp, and he can't touch Chesnaught outside of flamethrower. Obviously this core fits in with offensive teams. Zoroark adds almost no defensive synergy to the team outside of a psychic immunity, and Talonflame rips this core apart so a check (or two) is needed on the team. Hazard removal is also required since Mega Lop only takes 6% damage from SR, effectively ruining Zoroark's Illusion. Luckily if you haven't mega evolved Lop you can still bluff with rocks up though.
