EVs: 252 SAtk / 252 Spd / 4 Def
- Shadow Ball
- Hidden Power [Ground]
Standard movesets with a twist
Why it works: Haunter is a perfect user of Will-O-Wisp, allowing it to cripple many switch-ins that attempt to set up on it or take it down. Examples of this include Spiritomb and Klinklang. This can allow it to greatly deter the opposition's plans, and make it easier for Haunter and its teammates to destroy the opponent later on. With Eviolite equipped, Haunter and its Substitute can take hits from some Pokemon that it has burned, making it even more of a threat. Leftovers can also be used. however, as they can allow Haunter to set up more Substitutes. Haunter also poses a solid offensive presence, as not too many Pokemon can sufficiently take down Haunter without being crippled by Will-O-Wisp.
Positives/Negatives: Psychic-types can be good partners for this set since Haunter can cripple Spiritomb, making it easier for the aforementioned Psychic-types. Gothitelle is a perfect example, , as it can trap and KO things such as Cryogonal and Clefable that can easily wall this Haunter set. Pokemon that can set up are also good choices, as Haunter can cripple the enemy. However, it is still relatively fail, and isn't extremely strong.
