I like seeing others thoughts to see if I can make some tweaks to the team. I feel like I should have Swords Dance on Tapu Bulu, but IDK what to replace for it.
A few things to explain for good measure:
•I don't see a point in making a stat go over 400(other than Regieleki's speed for Electro Ball), so Toxapex/Probopass/Wo-chien only have up to 400 in one defensive stat, and the rest invested into their other defensive stat.
•Leads are Probopass(Stealth rocks/Sun, Sturdy ability makes sure I get at least one thing off/Rock tomb to slow the opposing lead down for whoever I volt switch into), Toxapex(Toxic spikes/Haze against stat boost leads), and Wo-chien(Lock a hazard setter into battle so I can KO it and clear the Hazards with Regieleki's Rapid spin[Rapid spin makes electro ball do more damage as well]).
•I always like to have a funny gimmick mon thrown on my teams. This teams mon is Trevenant. It makes my opponent a grass type with Forest's curse, then goes Tera fire Tera blast boosted even more by the sun for massive damage. Since the sun is up, Harvest lets me eat my Sitrus berry every turn too so I stay alive. Even after going Terra fire, Horn leech is still STAB, and gets a 30% damage boost from Grassy Terrain which means I heal even more from it.
•Regieleki doesn't have damage cut from burns, can't be paralyzed, and can't be frozen while the sun is up. So since putting it to sleep is an out, it has sleep talk instead of the usual explode since I'm using a Special Attack build.
•Regieleki is used to finish a weakened team off, so it is reserved until later so its red card doesn't pop early. Red card is used to get rid of mons that set up after Toxapex feinted, reserve momentum against mons with priority, and get me out of a tough spot volt switch can't put in the work for. IDK if it should be swapped for Life Orb or not though.
•I think it's a lesser known fact, but Grassy Terrain cuts damage from Earthquake/Magnitude/Bulldoze in half, so my ground weakness is less persistent.
Let me know if you have any questions on how the team works.
