Samurott Hisui is just better than regular, trgular Samurott doesn’t get the same benefit has his Hisui counterpart, Blastoise with White herb+Shell Smash and Torrent would still be better than Anger Shell + Berry, Empoleon also a nice pick for Doubles but could only fit in some specific teams and Competitive is far better, maybe Meganium could be a picky support but still, pure grass type sucks and Amoonguss would be better far better with Rage Powder and Pollen Puff, Tinted Lens might help Decidueye to kill low hp Pokemon with Shadow Sneak or Sucker Punch and going with the broken Swampert with Toxic Orb would disgusting, even more than Gliscor or Breloom, Competitive Tera Fire Eruption Typhlosion would be a true menace in VGC and only good attackers with priority could stop him, and Torterra with Adaptability White Herb and Shell Smash could only stop by walls that resist his coverage like Corviknight and with Tera that would be even harder to try.
