Mimikyu @ Rocky Helmet
Ability: Disguise
Level: 50
Tera Type: Normal / Stellar
EVs: 228 HP / 252 Atk / 20 Def / 4 SpD / 4 Spe
Adamant Nature
- Play Rough
- Shadow Sneak
- Curse
- Endure
By combining Rocky Helmet with Disguise, Mimikyu shows off its passive damage potential against contact attackers like Koraidon and Zacian-C. While its offensive profile may not be the focus of this set, it shouldn't be disregarded; Play Rough provides a lot of pressure in a meta filled with Dragon-types, and Shadow Sneak gives great cleaning power while forcing respect from Calyrex-S. Mimikyu can use Curse to further stack damage sources or punish targets like Leech Seed Calyrex-I that can play around Rocky Helmet. Endure can help seal a target's fate by buying an additional turn of Rocky Helmet and Curse damage. All these factors can create a hard time limit on sweepers and ruin their momentum. With the given EV spread, Mimikyu has enough bulk to survive Adamant Chien-Pao's Icicle Crash after Disguise breaks. Terastallizing Mimikyu is uncommon but can be done in a pinch, such as to block Ghost-type attacks with Tera Normal or power up Shadow Sneak with Tera Stellar or Tera Ghost.
