I checked the whole NU list and the ones unranked (and thus E-rank) are: Ariados, Banette, Beautifly, Beedrill, Bibarel, Bellossom, Carnivine, Chatot, Cherrim, Chimecho, Corsola, Delcatty, Delibird, Dewgong, Dunsparce, Dustox, Emolga, Farfetch'd, Fearow, Furret, Girafarig, Glailie, Granbull, Kecleon, Kricketune, Leavanny, Ledian, Lopunny, Lumineon, Lunatone, Machoke, Magcargo, Maractus, Mightyena, Minun, Mothim, Noctowl, Pachirisu, Persian, Parasect, Phione, Pikachu, Plusle, Purugly, Raticate, Regigigas, Seadra, Seaking, Shedinja, Shuckle, Slaking, Sudowoodo, Spinda, Sunflora, Swalot, Togetic, Unfezant, Unown, Vanniluxe, Vespiquen, Walrein, Watchog, Whirlipede, Whiscash, Wigglytuff, Wormadam, Wormadam-Trash, Wormadam-Sand. Of these, I think some of them should move up to D rank. Banette because of his TR lead set and TR is very anti meta atm. Bibarel because of Simple giving him a niche even though he is easily walled. Leavanny because it's great as a offensive supporter or an all out attacker due to forcing switches, even though it's speed it just below what you wanted it to be. Lopunny for Klutz and Switcheroo shenanigans, fake out and speed. Lunatone because Solrock is in D and i don't see why Lunatone is inferior. Machoke for No Guard DynamicPunch and good bulk. Magcargo has a very underrated lead SS set to catch opponents off guard. It's faster than you would imagine. Mightyena has Moxie and i guess it could make nice use of that. Sunflora could potentially be a TR attacker. Whirlipede is still pretty good at hazard setting and Swalot for being awesome.
