After using Inkay extensively, there are two roles I've found that personally suit Inkay the best, and unfortunately, Contrary Superpower is not one of these. The primary reason for this is that super-popular mons like Meditite, Swirlix, and Gligar resist it and also beat Inkay outright, preventing it from achieving the Contrary Superpower sweeps so many of us initially anticipated. It also doesn't help at all that Superpower is walled by Bug-types and their STAB attacks have a 4x type advantage against Inkay in return. Ouch. Anyway, let me get into what I've found to be the two best uses for Inkay in XY Little Cup:
Sweeper Stopper Inkay
Inkay @ Choice Scarf
Ability: Infiltrator
Level: 5
EVs: 16 HP / 252 Def / 236 Spd / 4 Atk
Impish Nature
- Switcheroo
- Topsy-Turvy
- Foul Play
- Destiny Bond
This set is equipped with just about every tool needed to stop setup sweepers from getting out of hand and developing into a crisis for the rest of its team. Choice Scarf allows Inkay more Speed to be able to better perform its role, and can be used in conjunction with Switcheroo to cripple the enemy, completely locking them up if they use a setup move on the turn Inkay forces an item swap, while also depriving them of their precious Berry Juice or Eviolite for Inkay's own use in the same turn. Topsy-Turvy, a move exclusive to Inkay and its evolution Malamar, greatly punishes any setup sweeper by converting all of their boosts to stat drops, and can quickly turn a formidable foe into a total weakling. STAB Foul Play is an alternative option for punishing physically inclined sweepers and also deals pretty good damage apart from that (142 Base Power move that is dependent on the target's Attack stat) and keeps Inkay from being Taunt bait. Destiny Bond is a last resort for bringing down a problematic foe, but if push comes to shove, it gets the job done. Not only does this set screw with setup sweepers that operate on their own, but it also throws a huge wrench in Baton Pass chains with Topsy-Turvy; there is no greater insult to Baton Pass chains than this move. The icing on the cake for this set is the ability
Infiltrator, which allows Switcheroo and Topsy-Turvy to do their job even if the enemy sets up a Substitute in an attempt to block Inkay's status moves. Being able to lock a foe into Substitute after it puts one up is hilarious. EVs can be shifted around to give Inkay more special bulk, but the given spread gives Inkay 21 Speed with Choice Scarf so that it can outspeed the entire unboosted tier before giving it up. This set would be so much more awesome if Inkay had access to U-turn, but it unfortunately does not get it.
Baton Pass Anchor Inkay
Inkay @ Berry Juice
Ability: Suction Cups
Level: 5
EVs: 164 Atk / 140 SAtk / 76 Spd / 68 SDef / 12 Def / 12 HP
Bashful Nature
- Psycho Cut
- Night Slash
- Return / Taunt
- Flamethrower
Yes, this set uses a flat nature that doesn't boost or decrease anything, while having an EV spread that provides all even numbers, because at the stage where it will be used, it will need to make the most of the boosts it gets passed, and it will likely need all of its stats to not be hindered by its own nature to achieve the highest efficiency. Psycho Cut and Night Slash are both attacks that Inkay gets STAB from, and also are both moves that score critical hits 100% of the time after Inkay is passed a Focus Energy boost; after receiving multiple boosts from the likes of Torchic, Mienfoo, and Mime Jr., Inkay will be hard to stop and no amount of defensive boosts or Screens will save the opposition. Flamethrower roasts the Steel-types that otherwise wall the set; Superpower is not used because it will take away the boosts that make it the only reason to use this set. Suction Cups keeps Inkay's boosts from being forcibly stripped from it by moves that force a switch, as well as Red Card. I have used Baton Pass extensively for several generations and I can say that it is awesome if you know what you're doing; for players who are new to this kind of team, it will take some getting used to for it to even make sense as a usable playstyle. This set can have trouble with Fairy-types, but +2 Psycho Cut easily OHKOs Swirlix on a critical hit, which is guaranteed if Focus Energy is part of the Baton Pass chain.
Inkay has some interesting things going for it, and it is not the best Pokemon competitively, but these sets are the absolute best uses I've found for it so far, if anyone would ever like to try it out. ♥
