Life Orb Clawitzer is a hidden gem in Reg M-B

I was looking at the Staraptor-Raichu Y team that has been popular recently and wanted to give an unique take of it (raptor is cringe and so is cringegambit). And while on the hunt for a different trick room abuser that matches well against other Kingambits, Sinistcha and Incin, I found Clawitzer. With its ability Mega Launcher, it basically gains STAB boosts on pulse moves, most notably Dark Pulse (so that the team doesn't lose coverage). Then I slapped a life orb on it, give it max sp.attack and a beneficial nature and the calcs looked incredible:

32+ SpA Life Orb Mega Launcher Clawitzer Aura Sphere vs. 32 HP / 2 SpD Chople Berry Kingambit: 208-247 (100.4 - 119.3%) -- guaranteed OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Water Pulse vs. 32 HP / 20+ SpD Incineroar: 174-211 (86.1 - 104.4%) -- 25% chance to OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Dark Pulse vs. 32 HP / 0 SpD Basculegion: 234-278 (103 - 122.4%) -- guaranteed OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Dark Pulse vs. 32 HP / 20 SpD Sinistcha: 187-221 (105 - 124.1%) -- guaranteed OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Dark Pulse vs. 25 HP / 15 SpD Farigiraf: 213-252 (96.8 - 114.5%) -- 81.25% chance to OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Water Pulse vs. 11 HP / 0 SpD Mega Delphox: 174-205 (108 - 127.3%) -- guaranteed OHKO

32+ SpA Life Orb Mega Launcher Clawitzer Aura Sphere vs. 32 HP / 25 SpD Archaludon: 203-239 (103 - 121.3%) -- guaranteed OHKO

It also one shots Gholdengo, M-Aerodactyl, M-Froslass, M-Tyranitar (in sand) and M-Metagross, two shots Garchomp and Venusaur, almost always 2HKO Zard Y in sun and M-Staraptor (though I don't include calcs here for the sake of not making this post too long) while also having respectable bulk, allowing it to throw off 3-4 attacks with life orb recoil even after a neutral hit.

The biggest challenge in using Clawitzer is its speed. With a base 59 speed, a negative speed nature lets it end up at 71 speed, which is slightly problematic since Kingambits either invest their last 2 points into Sp.Def (70 speed) or Speed (72 speed), while sometimes splitting between the two. This is something that is worth watching out, although Clawitzer always live one attack from a Life Orb Kingambit so at worst it's a trade.

Haven't seen anyone post about this guy so I thought it could be worth it :)
