[.TraX.]

Piloswine
Ancientpower/Rock Slide/HP Rock
Curse
Body Slam/Return/Blizzard
Earthquake
~ Seen this before, I found Pilo without rest to be very uninspiring against 99% of teams.

Magcargo
HP Dragon/Rest
Amnesia
Acid Armor
Flamethrower
~ Ditch thrower and amnesia for curse and earthquake, works well if you get like 3 agilities passed to it and bring it in to a blissey.

Dunsparce
HP Ghost/Iron Tail
Curse
Return
Ancientpower/Rock Slide/HP Rock
~ Never liked curse without rest, never liked dunsparse without Glare.

Arcanine
Dragonbreath
Crunch
Flamethrower
HP Grass/Extremespeed
~ Weaksauce, arcanine doesnt have the spatk for this setup.

Parasect
Sludge Bomb
Spore
HP Bug
Swords dance
~ Needs agility passed or it sucks, if it gets agility it can still suck if you play with sleep clause, Stun Spore is awesome.

Ariados
HP Bug
Return
Nightshade/Curse
Sludge Bomb
~ nope, it isnt better than I think, it's deader than you think.

Octillery
Psybeam/HP Electric or Dragon
Surf
Ice Beam
Flamethrower
~ Don't even try to use dragon moves on anything in gsc (kingdra is exempt but still not good), dragon sucks.

Gyarados
Hydropump
Endure
Reversal
HP Flying/Return
~ too slow for endure/rev in GSC, whatsmore Gyara is pretty uninspiring in the attack department anyway.

Hate to be over critical but these kind of setups don't work too well in GSC (I suspect you may be a ruby/saphire player). The difference in generations is huge, most of this stuff would be passable in r/s.

This is NOT for Netbattle :/

OMG I might loose against a Lv.3 Hoothoot!!! :0

In-game, these sets do wonders

For Gyarados, Reversal can be replaced with Flail, but It's not as good.

Then you should have specified as such.

[Rant=Ingame]I honestly dont have a clue why anyone needs an ingame team that isn't going to be used on stadium2, battle tower or in link battles rated, anyone could probably beat the elite 4 and lance with 5 decently typed pokemon over level 48.[/Rant]
