When it comes to Volt-Turn Mayhem UU (yes, they hold these tours in the Tours Plaza room in the main Showdown server), this is the Decidueye set I prefer:
Decidueye @ Rocky Helmet
Ability: Long Reach
Tera Type: Fighting
EVs: 248 HP / 252 Def / 8 SpD
Relaxed Nature
- Defog
- Shadow Sneak
- Roost
- Frenzy Plant
In Volt-Turn Mayhem UU, Decidueye's main edge over Brambleghast is its better match-up against the annoying Regenerator Alomomola, thanks to its better ability to use special attacks.
Shadow Sneak is great to let Decidueye deal chip damage and sneak away from faster mons, thanks to its +1 priority.
Long Reach prevents Shadow Sneak from proccing nasty stuff like Rocky Helmet and Flame Body.
Speaking of Rocky Helmet, that item is great at racking up chip. Decidueye has access to reliable recovery, anyway.
Tera Fighting fixes most of Decidueye's plentiful weaknesses.
I'd probably actually still prefer this Decidueye set in Volt-Turn Mayhem OU (i.e. the regular version). Priority is too good.
