New idea! Instead of running a conventional Trick Room Reuniclus, why not go a step further to outspeed the competition?
Reuniclus @ Life Orb / Leftovers
Ability: Magic Guard
EVs: 220 HP / 252 SpA / 36 Spe
Modest Nature (+SpA, -Atk)
- Thunder Wave
- Psychic
- Focus Blast
- Recover / Shadow Ball
With minimal speed investment, the abysmally slow Reuniclus is able to outspeed even Scarf Heatran after it hits it with Thunder Wave, a move that I wasn't even aware Reuniclus could learn. An advantage over Trick Room is that the paralysis it provides is much more permenant than the effects of Trick Room, and doesn't necessitate the use of other slow attackers to be effective. Whilst the opponent can get a hit in before you paralyse them, and whilst Ground types are immune to Thunder Wave, Reuniclus has enough bulk to take a strong neutral hit and I can't think of a single Ground type that likes taking one of Reuniclus' attacks.
The thing is, you only run a Trick Room Reuniclus on a Trick Room team, which is helped a lot more by Trick Room, surprise surprise.
