I'm not gonna touch mine.
Absol can definitely destroy both of them, and gets passed that damn Trick Room with a powerful super effective STAB priority move. However, it can't switch in reliably unless Slowking used Psyshock/Trick Room or Escavalier used Pursuit. Your attacks are also extremely predictable against both of them, so you have to make that risky prediction as to whether or not it's gonna stay or switch.
Medicham is certainly very powerful and can deal with both while in, however it can only switch in on Slowking (or a pursuing Escavalier), and even then it would barely survive (against Slowking). Also, if Trick Room is active, you've signed your death warrant.
Manectric is an excellent revenge killer, very fast for the tier with two good moves to OHKO each. However, unless it's switching in on an Iron Heading Escavalier, it will die or (in Slowking's case) go down to the 20's at least, leaving you with only one or two attacks before death and possibly DOA with hazards. Also, assuming he already attacked, you only have a 2/3 chance of OHKOing Slowking. Also countered by Trick Room.
Quagsire is an excellent switch-in option, although that's about it. It can handle Escavalier pretty well, but doesn't really do much against Slowking.
Druddigon...I'm sorry, but that set is just bad. Give it back its speed IVs, replace Thunder Punch with Sucker Punch (allows you to bypass Trick Room and hit Slowking for super effective, also more useful overall and still gives you perfect coverage), replace Flamethrower with Fire Fang, make it Adamant, and take the EVs out of Satk and put them back into HP (Fire Fang with Sheer Force and max+ Atk does more than Flamethrower with your set).
Qwilfish is great for switching in, especially on Escavalier, due to its key resistances, bulk, and attack-destroying ability. However, it can't do much while it's in against Slowking, who can take out 80-90% hp in one hit. Solid aside from that, though.
Magneton absolutely destroys Escavalier, but not so much Slowking. It has nothing to get past Trick Room and it takes massive damage unless it uses Psyshock. Also, the sub is kinda useless. I'd recommend switching it with Flash Cannon.
