Rotom-W Rotom-W is unchanged from the new Generation, but the metagame around it is vastly different. Boasting an amazing typing which allows it to take and give attacks well. Levitate is a great ability for Rotom-W, leaving it weak only to Grass type attacks. Defensive base stats of 50/107/107 may not look impressive, but Rotom-W's useful resistances helps to offset that. Volt Switch is a great move for Rotom-W to have and it can be used to grab momentum when it has been lost. Rotom-W has good support options to cripple the opponent's Pokemon. Rotom-W will surely remain to be an important threat in the XY OU metagame. Bulky Pivot Rotom-W @ Leftovers / Chesto Berry Trait: Levitate EVs: 252 HP / 252 Def / 4 Spd Bold Nature (+Def, -Atk) - Hydro Pump - Volt Switch - Pain Split / Rest - Will-O-Wisp This set is the standard for Rotom-W and takes full advantage of Rotom-W's Defensive typing. The investment in Defense allows Rotom-W to defeat threats such as Talonflame and Mega Pinsir. Hydro Pump hits fairly hard and can hit Ground types that are immune to Volt Switch. Volt Switch hits Flying types from whom Rotom-W can normally handle well while gaining momentum by allowing you to switch Rotom-W out after using the attack. Will-O-Wisp is useful for crippling Physical Attackers and can help wear down walls that would otherwise hinder your team. Rest, if Chesto Berry is your item, will heal Rotom-W to full health at the cost of your Chesto Berry. Pain Split is situational, but can restore Rotom-W's health back when used on an opposing Pokemon with high health. 44 Speed can outspeed Jolly Belly Drum Azumarill and Jolly Mawile, but they are rare enough to overlook that fact. Choice Rotom-W @ Choice Scarf / Choice Specs Trait: Levitate EVs: 252 SAtk / 4 SDef / 252 Spd Timid Nature (+Spd, -Atk) - Hydro Pump - Volt Switch - Trick - Thunderbolt / Will-O-Wisp Rotom-W lacks great Speed or great Special Attack, and a Choice item can remedy this. Choice Scarf augments Rotom-W's poor speed and Choice Specs augments Rotom-W's average Special Attack. Hydro Pump hits very hard, even without Choice Specs. Volt Switch can be used to gain momentum and hit hard or fast depending on item. Trick can cripple walls such as Chansey. Thunderbolt is useful to have since Volt Switch hits pretty weakly. Will-O-Wisp is used after the Choice is tricked away, or in a pinch to cripple something that needs to be crippled immediately. Modest is an option to use instead of Timid, but the Speed is generally more appreciated. Other Options Thunder Wave can be used instead of Will-O-Wisp on the Bulky Pivot Set. Hidden Power [Fire] can be used on the fourth slot of the Choice Set in order to defeat Ferrothorn. Specially Defensive Rotom-W is still usable, but does not take full advantage of Rotom-W's typing like a Physically Defensive set can. Hidden Power [Grass] is an option on the Choice set to hit Gastrodon. Hidden Power [Ice] can be used, but even when it hits super effectively, it's laughably weak. Checks and Counters Mega-Venusaur can take anything Rotom-W can do easily and 2HKO with Giga Drain. Chansey and Blissey don't care much about status and can wear Rotom-W down with Toxic stall, but they don't want to be Tricked by a Choice set. Bulky Grass types in general are a really good way to defeat Rotom-W. Assault Vest Conkeldurr can take two of any attack from Rotom-W, except a Choice Specs Hydro Pump, can use Drain Punch to hurt Rotom-W and heal back at once, and if Rotom-W tries to burn Conkeldurr, it will just make Conkeldurr hit harder. Gastrodon can take anything from Rotom-W barring a Hidden Power [Grass] and Toxic Rotom-W back. Goodra, Latios, and Latias don't mind anything from Rotom-W except a Thunder Wave which cripples Latios and Latias, all three can do massive damage to Rotom-W with Draco Meteor.
