>>31469864>MarowakYou're wasting 4 EVs. Either take 4 more from HP to put them in SpD, or the other way around.
>MukGunk Shot is bad, so is Crunch. Swap them for Poison Jab and Knock Off, since they're way more reliable and useful in the meta. Brick Break isn't that great, but if you really want to break Aurora Veils, I suppose it's alright. Alternatively you could run Shadow Sneak (bad damage, but useful for picking up stuff at 5%), Taunt or even Imprison for the mirror.
>VikavoltString Shot is cool, but if you're giving up a move slot for it, you'd better run Thunderbolt instead of Discharge, since nothing can really take it without fear other than the Marowak.
>GyaradosInteresting choice, and could definitely work in BO1s. Nothing really wrong with it.
>DrampaHyper Voice doesn't do that much damage in practice, I think you should change it to Draco Meteor to nuke shit.
>PorygonI think Thunderbolt would be more useful than Shadow Ball, but that's really up to you. It's not a wrong choice.
Another thing is that, since you're running almost hard TR, you should have something like Hariyama somewhere to make P2's job easier.
Also, the spreads are a bit unoptimized for a few Pokemon, especially Marowak's. I recommend you to head over Wolfe's channel to get some sample spreads from him. Trainer Tower has some too, in case you want alternatives.
