I'm going to use the alt : [nu] RW Alex.
At first I was going to use Kelcon but I found it really under whleming at doing everything bar getting hazards up. So now I'm going to use Stunfisk who makes a really good partner for a number of pokemon in the tier.
I'm just using a RestTalk Stunfisk to prolong his bulk and spread status with Scald and Discharge. A lot of the time you rely on sleep talk hitting the right move at the right time but I seem to have been rather lucky so far. People do under estimate him and try to set up and even if I get unlucky and don't get one of the status on the set up user I can usually capitilise on Stunfisks death thanks to the partners I've selected. Cacturne in particular is an amazing partner since Stunfisk will often force some things out due to its immense bulk meaning more hazard damage, thats not to mention that Cacturne can take some water and grass attacks aimed at Stunfisk especially if you elect for Water absorb over Encore.
