Offensive Trick Room (OTR) Hatterene
Hatterene (F) @ Life Orb
Ability: Magic Bounce
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk / 0 Spe
- Trick Room
- Psyshock
- Mystical Fire
- Dazzling Gleam
This Hatterene functions on Trick Room teams, and rather than just getting Trick Room up and going into a Trick Room abuser, this Hatterene aims to abuse Trick Room itself. A Modest max SpA Hatterene reaches an impressive 408 SpA, with Life Orb boosting the damage output even further. Hatterene's natural bulk means it will usuallly be able to set Trick Room up for itself to begin attacking as well. Finally, even if Hatterene goes down while attacking, another Trick Room abuser can be brought in for free while Trick Room is active afterwards, meaning Hatterene is still contributing even after it faints. Dazzling Gleam was chosen over Draining Kiss for this reason - longevity is not as important as doing damage for this Hatterene after Trick Room goes up.
Assault Vest
Hatterene @ Assault Vest
Ability: Magic Bounce
EVs: 252 HP / 140 SpA / 112 SpD
Modest Nature
- Future Sight
- Psyshock
- Dazzling Gleam
- Mystical Fire
Assault Vest allows Hatterene to live more hits than usual and hit back with its good coverage and decent power, and it also provides utility with a powerful Future Sight. The given spread is to live Choice Specs Aegislash's Shadow Ball from full, but more or less bulk is an option.
Healing Wish Hatterene
Hatterene (F) @ Life Orb
Ability: Magic Bounce
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk / 0 Spe
- Trick Room
- Psyshock
- Healing Wish
- Dazzling Gleam
This set underlines Hatterene's good traits (low Spe, high SpA and good natural bulk), including its ability that prevent Taunt from being effective.
Psyshock + Dazzling Gleam is the dual STAB combination, and is quite effective with 252 SpA+ EVs.
Trick Room can be useful to use that low Spe stat alongside Life Orb + Magic Bounce that negates the recoil.
Healing Wish is an underrated supporting move that allows you to exchange a (weakened) Hatterene for a fully recharged teammate, such as a cleaner or a sweeper. Take in account that Hatterene doesn't have Regenerator (unlike Reuniclus) to restore its own health, so it is destined to perish anyway: Healing Wish is a good way to differenciate itself from Reuniclus.
