Linoone in this meta loses STAB on ExtremeSpeed in exchange for more STABs walled by Steel types. Shame, if it got fighting or ground it could have been really good.
Tyranitar has the atrocious typing of Bug/Grass. RIP
Scyther retains it's 4x weakness to Ice, dropping it's bug typing for an ice typing. What a pity.
Pokemon with STAB Boltbeam include: Geodude, Mothim, Palkia (banned, but still),
Pokemon with STAB Ice/Ground include: Hitmonchan, Rhydon, Shuppet, Infernape, Weavile, Lickilicky, Meloetta
Pokemon with Fairy/Steel typing (best defensive in the game): Vulpix, Surskit, Camerupt, Gastrodon, Unfezant, Barbaracle
Despite Mothim's meager stats (70/94/50/94/50/66), access to Quiver Dance, STAB boltbeam, and Bug Buzz to bypass Substitutes would be a interesting threat in lower tiers.
Infernape is a gigantic threat with it's excellent new typing. Speedy at Base 108, perfectly capable of going both physical and special with 104 in each stat, and a plethora of attacks including Ice Beam, Earthquake, Icicle Crash, Earth Power, Ice Shard, Flare Blitz, Mach Punch, Fire Blast, Vacuum Wave, Flamethrower, ThunderPunch, Close Combat, and Grass Knot, Infernape becomes ridiculously powerful. Sets I think would work great for it are

Very scary indeed.
Also, Camerupt has the best defensive typing in the game, along with Solid Rock to take EQs and Flamethrowers better. Pretty good, I'd say.
