Swords Dance Tangrowth is meant to be used on bulky offensive teams as a breaker of sorts. The idea of this set is pretty simple tbh. You use Tangrowth's excellent physical bulk to get into the game, force switches, and set up a Swords Dance easily, and then try and do as much damage as possible from there. Even if Tangrowth fails to cleanly sweep because of its poor Speed, it'll still most likely inflict some serious damage on the opposing team, and it'll probably be able to get back into the game later thanks to Regenerator unless you let it die completely. Swords Dance and Power Whip are givens as the move Tangrowth uses to boost and its most powerful physical STAB move, respectively, but picking the other two moveslots isn't so simple. Knock Off is as always a great option for the damage and coverage it provides, not to mention its ability to remove the items of Pokemon that'd like to switch in on Tangrowth, whether its removing an Eviolite from Golbat, Leftovers from an Amoonguss, or Life Orb from a Moltres. Alternatively, Rock Slide can be used to nail Moltres, Fletchinder, and Mega Abomasnow on the switch, all 3 of which are pretty big threats that tend to switch into Tangrowth quite often. Hell, even Sleep Powder can be used in this moveslot to gain some more set up opportunities with Swords Dance. Earthquake is used in the last moveslot to hit Steel-types such as Cobalion, Registeel, and Doublade, but Knock Off can also be used here if you aren't using it in the third moveslot. The EVs maximize Tangrowth's Attack and give it enough Speed to smack Alomomola with a Power Whip before it can use either Wish or Toxic, while the rest are thrown into HP to increase Tangrowth's overall bulk.
This set might seem like it recieves a lot of competition from Swords Dance Virizion, but i'd argue it plays quite differently tbh given the obvious differences in stat spread, movepool, and Tangrowth's extra longevity. (For example, SD Virizion is hard countered by Doublade, but SD Tangrowth easily beats it as long as it has one of Knock Off or Earthquake)!
Likewise, it has more longevity (Regenerator, Grass STAB doesn't do recoil, no rocks weakness, better typing), more physical bulk, more speed, and the possibility of Sleep Powder over SD Mega Abomasnow
Anyways, this is the best i can think of right off the bat outside of some kind of Choice Set, which another user already said he was gonna post over irc.
