Beheeyem is an easy A+ Pokemon at the moment. It is by far the hardest hitting Pokemon in the tier thanks to its Analytic ability combined with its very strong 125 Special Attack stat. It has absolutely zero switch-ins; Psychic/T-Bolt/Signal Beam practically nails everything in the tier hard enough on the switch that giving it free switch-ins will lead to a KO. OTR is a really good cleaner, and although Analytic isn't nearly as useful in Trick Room, its still very strong enough to muscle through most offensive teams. LO 3 attacks with something like Sub or Recover in the last slot can rip apart bulkier teams while leveling anything found on offense. Beheeyem is also bulky enough to withstand most neutral attacks, so it's not like it has to rely so much on its raw firepower to get by. It could definitely warrant a spot in S-, but with Krow, Scarf Krook, Eviolite Zweilous, CB Jask, and Dark coverage being a pretty common filler in FU, Beheeyem is by no means difficult to check. A+ seems very fit for it.
Simipour will join the other monkeys in S-, but will move up to S. Specs is extremely powerful and has basically zero reliable switch-ins outside of Politoed. Scarf is a solid revenge killer that cleans up offensive teams pretty well and has great coverage options. Nasty Plot is an insanely good sweeper that can muscle through nearly everything and with Sub it can set up on a lot of its checks, such as Tortle and Prinplup. I personally thought it was S- even with Goat around, but now that it's gone, Pour just finds it so much easier to spam Water moves. If Simisear is S-, I don't really think Simipour should be ranked lower than it, and vice versa, as long as Rapidash is absent.
The return of Relicanth and Luxray doesn't do too much to the tier, but both are
solid B+ Pokemon, and were before they left. Relicanth has a lot of common weaknesses, but it's a very strong hole puncher with recoilness Head Smash, and much like Gigalith it's a solid Custap Lead with a recoil Head Smash and Sturdy to act as sort of a pseudo spin blocker. It's also the BEST lead for rain teams, as it is able to set up SR and Rain Dance very reliably thanks to Sturdy. Luxray can run a very solid Choice Scarf set that revenge kills the monkeys/Krow and hits pretty damn hard and with Intimidate it can pivot into other Pokemon to better take hits. CB Intimidate is also pretty neat as well.
Carbink is also going to B for its niche as a SR/weather lead on sun and being a very solid check to a few top tier threats such as Fraxure, Zweilous, Murkrow, Raticate, and Cuno to an extent.
