Question

1. Haxorus-lead(no weather)
   Taunt
   Dragon dance
   Earthquake
   Dual chop

He mainly taunts set up pokes and then I use DD.

1. Dugtrio-Lead (Weather)
   Substitute
   Endure

It's to defeat the weather starters mainly ninetails and t-tar. With endure ima have a berry that increases atk, so if I battle politoad, it'll deal some damage.

5.Gengar- Special Attacker
Substitute

Pretty straight forward

6.???

P.s I know I'm missing ev's, natures and Ivs but that's not really important in this case, the roles should be enough, I just need help deciding on a 6th pokemon. Suggestions? Oh and on the moves marked ???

Answer 1

for Jellicent, go with this moveset:
recover
will-o-wisp
hex
surf

for Gengar, you want to have all out attacking moves:
thunderbolt
shadow ball
Giga drain ( this works great with a life orb)
focus blast/ psychic

As your last pokemon I reccomend a tank, like Swampert:
EV's: 252 att/ 252 sp def/ 4 hp
nature: (+att -sp att) or (+sp def -sp att)
moves:
Waterfall
Ice punch/ avalanche
hammer arm
earthquake

It's hard to answer without EV's but I hope this helps :)
