to stimulate some discussion:
What are some pokemon that would be so much better with just a small change?
I bet you can guess what I think it should be..
That's right! It's Klawf!
Klawf with +20 to any of Speed, HP, or Attack becomes legitimately OK in OU. Klawf's coverage isn't terrible actually. It gets Stone Edge, Knock Off, High Horsepower, Crabhammer, Trailblaze, Swords Dance, and Stealth Rock. That means that it can hit the majority of OU pokemon for super effective damage. Certain things still wall it, such as DonBrozo and Corv, but it still Knock Off or SR on the switch to make progress, and it can still hit them hard if they were predamaged. It's main issue is its stats. They are just barely enough to be passable when invested, but unfortunately you want to be invested in speed for Gambit/Anger Shell tomfoolery, attack so you can actually do damage while you regenerate that Life Orb damage off, and HP/SpDef so it can switch in on weaker special attacks like Flamethrower from Glowking and threaten it with Knock Off/Horsepower OR so that it can get up a lategame swords dance and clean up. With the boosts, it is no longer pressured for EVs and can choose to be more balanced, investing in its non-boosted stats, or purely defensive or offensive investing in the boosted stats. It could even run things like Assault Vest or Choice Band for survivability or damage, not worrying about lack of longevity thanks to Regenerator. Anger Shell could also be a sort of lure, as you assume that you should damage the Swords Dancing Klawf, but instead are surprised with 2.5x boosted attacks and 1.5x speed.
