PTrap Rain team

Hey everyone, I’m fairly new to the VGC aspect of Pokemon, and I really like the Perish archetype, I’ve been trying to look at a few videos and stuff like that and I came up with this team. Mega Gengar being obviously the main piece of the team with Disable to be able to remove those super effective moves against him. Politoed as secondary endgame Perish user + drizzle ability to support Archaludon and Klefki. Rillaboom for half ground damage with pivoting and priority. Simple Archaludon build. Toxapex a bit more of an offensive one with venoshock critting everytime someone is poisoned and also infestation helps keep opposing Pokemon in the field. Klefki with screens, rain dance in case of weather teams to keep my rain weather going and fairy lock found interesting as a source of making sure even if I mess up my pivoting and repositioning during perish counters with Shadow Tag from Gengar, I can lock everyone on the field for the next turn which is pretty nice. Let me know what you guys think about the team, I’m open to anything. EVs everyone is just build bulky since the team doesn’t really go around damage output.
