I made this team before, but I remade this, and, after testing a few times in Pokemon Online, find it works fairly well, but still want some advice on it. Please note that this is only my second doubles team to ever make. I also just measured the EVs pretty quickly, so don't judge those too harshly, if they seem a bit random.
-Ninjask-
@Leftovers
Jolly
~Substitute
~Swords Dance
~X-Scissor
~Baton Pass
152 HP / 148 Atk / 188 Spe
All he does is sets up, while Clefable keeps him clear of attacks. The X-Scissor is just so he isn't completely helpless
-Clefable-
@Leftovers
Impish
~Follow Me
~Thunder Wave
~Softboiled
~Protect
255 Def / 255 SpD
Clefable is bulky enough to take a bunch of hits, and it uses the Follow Me all the way through, just getting the T-Wave status condition up in between. The Protect is a just in case, or if it is still alive if Gengar explodes later. It also has the Softboiled, obviously, to keep itself alive. And, it can, time and time again, keep its HP up.
-Scizor
@Life Orb
Adamant
~Bullet Punch
~Pursuit
~Super Power
~Baton Pass
80 HP / 220 Atk / 152 Def / 56 SpD
Scizor is one of the few things to Pass into. It has the Bullet Punch to out speed anything, the Life Orb to power up attacks, the Super Power just for the sheer stength, and Pursuit as a nice way to stop your opponent from retreating. It then has the baton pass once it gets beat up enough. I have his EVs set so he not only can attack well, but can also take a few hits.
-Gengar-
@Life Orb
Modest
~Explosion
~Shadow Ball
~Thunder Bolt
~Focus Blast
252 SpA / 252 Spe / 4 SpD
Gengar just has the coverage to do what's needed, and then, when at low enough HP, making sure that the other Pokemon has a sub setup or Protect, explodes.
-Ramparados
@Life Orb
Adamant
~Earthquake
~Thunder Punch
~Crunch
~Stone Edge
255 Atk / 128 Def / 124 Spe
This Pokemon is just powerful and has great coverage overall. Once you have the pass into it, the EQ can just entirely dominate, and if you try to resist it, Thunder Punch takes care of you. The crunch, obviously takes out the Ghosts, and the Stone Edge is also there as a threat.
-Togekiss
@Leftovers
Impish
~Wish
~Substitute
~Baton Pass
~Heal Bell
32 HP / 220 Def / 220 SpD
This is just to switch into in case you need to. It sets the sub up. Gives the heal bell, and then just wishes and passes back out.
