Well, those stats are amazing for a LC, so I should say it can be instaban. (Type: Null)
Alola Rattata is going to be strong as hell, but just only for deal a few hits and then, fall. it has a good Speed base and monstruous Attack thanks to Hustle, but it's case of luck, due to the accuracy getting lowered. Also, it's defenses make it a frail mon.
Alola Sandshrew, SLUSH RUSH, my dream became true. It can be a good way to try an Ice Spam this gen, if Alola Pix has Snow Warning, as I said months ago. Reaching 14 Speed and under hail 28 can make it a great sweeper, thanks to its 75 Base Attack, dealing great damage to Grass-types like Foongus, which it could stop him before becoming Alolan, and Fairy-types such as Spritzee and Snubbull. Its 90 Defense base makes it too hard to beat for the physical side. With Swords Dance and under hail, stopping it with Timmy could be the only way to not be swept by this beast.
Alola Vulpix, ok, it became true. It has Snow Warning, so it's a great partner for Alola Sandshrew, non-failing Blizzards, and giving 2x Boost of Slush Rush to Sandshrew. It could be cool if it got Moonblast, being a good way to deal good damage Dark-types as Scraggy. Also, carrying the Hail-boosting rock helps to keep the hail active.
Alola Meowth, what to say about him, it's typing and Technician makes attacks like Bite, KOff and Feint Attack more stronger than before. It must suck for Meowth to lose power on Fake Out, but it can be a good partner for a Dark Spam with Pawn, for example. But the thing of having more SpA can be useful for be a better Nasty Plot user, and 20 Spe makes it a beast.
Alola Geodude, so, new -ite ability, making Normal-type attacks to Electric-type attacks. It gets 4x weakness from Ground, so the way it was getting used won't change too much, in my opinion.
Alola Grimer, I so knew it that it could get Pursuit. Now it's going to be better Pursuit trapper than Stunky, it has good stats, and that combined with Poison Touch, it can be a good way to cripple a lot of mons. Power of Alchemy sound pretty cool in doubles, getting the ability of a fell partner.
Alola Diglett, welp, rest in peace, Arena Trap. But now, Tangling Hair is a ability which can low the foe's speed having contact with it, so it can make physical scarf users slower (sounds like Gooey). Also, its Steel typing allows it to switch into Fairy mons like Snubbull and Spritzee, without getting too much damage from thei Fairy STABs, and deal good damage with its Steel options, but it makes Rock Slide be more forgotten.
