Deoxys-A @ Focus Sash
EVs: 20 Atk / 252 SAtk / 236 Spd
Mild Nature (+SAtk, -Def)
- Shadow Ball
- Psycho Boost
I would like to suggest deoxys-a. Mild nature is used so that the combination of psycho boost and extremespeed kos lead kyogres. It can take on any lead and always come out on top. In team preview it is made to look like the life orb attacker to play mind games with the opponent. It takes out all the faster threats that reshiram has to deal with such as palkia and scarf kyogre. With Xatu's support it is likely that this will not die to entry hazards after that sash is used.
