This team has a pretty high success rate on Pokémon Showdown. I've gone through a few iterations before deciding on it, and have started IV breeding to construct the team in-game. However, I'd like some advice beforehand, because I'm very new to the metagame and may have missed some glaring errors with my team (aside from the obvious Water/Ground weakness). Klefki @ Leftovers Ability: Prankster EVs: 252 HP / 4 Def / 252 SDef Calm Nature - Swagger - Foul Play - Thunder Wave - Substitute This Klefki has been incredibly useful at completely stopping sweepers in their tracks, and my opponents generally find it difficult to take down. Aside from Magic Bounce Espeon, nothing really counters this thing. Swagger, Thunder Wave, get behind a Sub and Foul Play. Malamar @ Leftovers Ability: Contrary EVs: 252 HP / 252 Atk / 4 SDef Adamant Nature - Night Slash - Topsy-turvy - Superpower - Rock Slide I like the idea of using a Malamar, but I'm still a little unsure as to how to employ it. Sometimes I try to use it to shut sweepers down with Topsy-Turvy (which doesn't seem to be a typical move on Malamar, as people don't expect it). Other times, I use it as a Physical sweeper, Rock Slide being particularly useful as opponents don't expect it. However, it's difficult for it to do both effectively. Perhaps a change in hold item would help? Togekiss @ Assault Vest Ability: Serene Grace EVs: 252 HP / 64 Def / 64 SDef / 128 Spd Modest Nature - Air Slash - Aura Sphere - Dazzling Gleam - Flamethrower My favourite Pokémon is Togekiss, and I always see people talking about winning with your favourites, even in the metagame, so here it is. It's a bulky attacker, the Assault Vest allowing it to survive and keep spamming attacks. It has pretty good coverage, and with Rapid Spin support it's difficult to stop. Flamethrower over Fire Blast because I sometimes can't afford to miss Steel types. Rotom-Wash @ Leftovers Ability: Levitate EVs: 252 HP / 4 SAtk / 252 SDef Calm Nature - Hydro Pump - Volt Switch - Rest - Sleep Talk Special Wall. Between it and Trevenant, very little gets through. Simply RestTalk and go. I've found it great to switch in on moves, although its moveset can be limited at times. Excadrill @ Leftovers Ability: Mold Breaker EVs: 252 HP / 4 Atk / 252 SDef Careful Nature - Earthquake - Rapid Spin - Toxic - Protect Rapid Spin support. Chose to make it defensive so that I can keep it alive as long as possible. Toxic and Protect are there to finish off anything that's nearly dead and annoy the opponent. Trevenant @ Lum Berry Ability: Harvest EVs: 252 HP / 252 Def / 4 SDef Impish Nature - Rest - Will-O-Wisp - Curse - Substitute This set has been working really well. Basically infinite Sleep + Lum Berry. However, the lack of Horn Leech is a bit limiting, as Water/Ground Pokémon like Gastrodon are difficult to deal with.
