Hey! I just wanted some pointers. I do really well in Showdown but every so often I get stuck. Mainly I'm asking for my sixth slot.

Right now, I'm working on building a team around DD Feraligatr. My target is to take down the standard OU sets and be able to handle stall teams.

Feraligatr - late game sweep Sheer force/life orb - Dragon Dance - Waterfall - Ice Punch - Crunch

Klefki - late game set up for gatr Prankster/light clay - Light Screen - Reflect - Thunder Wave - Play Rough

Porygon 2 - tank/Lando counter Analytic/Eviolite - ice beam - thunderbolt - recover - hidden power (fire)

Alolan Muk Poison Touck/assault vest - tapu counter - knock off - poison jab - shadow sneak - clear smog

Mamoswine - lead Thick fat/focus sash - Earthquake - Icicle Crash - ice shard - superpower

My sixth slot has been slurpuff, porygon z, rotom-mow, togekiss, and mew

And suggestions? I might just be getting it all wrong but I can usually get to 1500-1600 in OU with a little time so I feel like I'm close.

Thank you very much guys, I look forward to reading your input :)
