Making your own sets does take a bit of practice, but offensive Gliscor is all I use for VGC. I can give you my set.
Gliscor @ Toxic Orb
184 Atk/ 72 Def/ 252 Speed
Impish/Adamant nature (depends heavily on what you want more, power or endurance)
-Earthquake
-Toxic
-Ice Fang
-Night Slash
Earthquake is your standard stuff, hits hard with STAB. Toxic is also pretty standard, you want stuff to take that residual damage. Ice Fang is ONLY for Dragons and Landorus, and Night Slash is for Sp.Def Cresselias. The Defense added to the set allows you to still take physical hits so that Poison Heal is worth it without sacrificing the ability to hit hard with EQ.
As with any unstandard set, change it to your liking, and if it doesn't work for you, don't use it xD
Ice Fang doesn't seem like it would be necessary for me - since this Gligar (Gliscor now, actually) is filling the spot on my Sandstorm team a Garchomp might have held I don't think I have much of a dragon weakness, and Landorus... well, yeah, I guess Rock Slide won't be enough for him. Hm.
Really, the only change I would need to make to that set is the inclusion of Protect and possibly Tailwind. Some HP EVs would be nice, as well... Also, the Gliscor I have is Naughty. I know it's not the best, but I figured that if I didn't take it I'd be soft-resetting for an hour and probably wouldn't get anything better. I'm still discouraged after trying to SR all three of my GameStop Meloettas and constantly getting everything but Modest multiple times. I settled for a Timid--which I can probably use in spite of bad Attack--and two neutral-natured ones with decent stats which I obviously won't EV train and might try to trade for better ones.
