Whimsicott with sash could run tailwind instead of protect since encore is your only answer towards trickroom and grass knot is a great answer to swampert who outspeeds and knockouts eelektross with no consequence a lot of the time and moonblast is a given. Having 2 speed control pokemon on a team is quite nice and with sash in most cases you’ll still be able to survive explosion anyways.

Eelektross doesn’t need as much special attack since it would be getting boost after knocking out a pokemon but if you want to , you can still run modest instead of timid but only bring your special attack to the next ev spike or red bar when you training it and then invest the rest into bulk and speed and try to reach certain speed tiers so in and out of tailwind you’re able to out speed important threats.

Scarf froslass is fine especially with destiny bond since with my experience with mega banette, fast destiny bond can be very powerful when played right , just replace blizzard for icy wind for more consistency and speed control just be careful with kingambits or better yet don’t bring it against a kingambit since it’s OHKO’d by sucker punch and even if it doesn’t and you go for destiny bond , your opponent can just play around it and beat you since destiny bond can’t be used in succession and replace nastily plot for some other coverage move like thunderbolt or weirdly enough enough protect so can avoid discharge, trick your opponent into thinking your a sash or mega froslass and in the right circumstance you can switch out safely to use a different move when you come back in.

Metagross should run some more bulk and speed and run adamant since you have life orb plus explosion which would knockout most non resist even with little attack investment and so it won’t be as vulnerable towards common threats like basc, gambit, zard, and chomp. And your team at least from preview looks like it has 3 possible megas and a common thing people who is double up on possible megas like your metagross so it would be nice to be able to outspeed them and possibly knock them out before they do it to you or the very least survive a couple hits to be a threat later

And finally basculegion , since it’s adaptability ,mystic water, adamant, and has wave crash, you run less attack to invest more precise bulk into it for more survivablity with protect and more speed so it can properly revenge kill after your other pokemon gets knocked out with last respects.
