Dark Fallen Angel
FIDDLESTICKS IS ALSO GOOD ON MID!
What's the point of using Choice Specs, when Reuniclus, thanks to Magic Guard, takes no damage from Life Orb? I know that you habe Trick, but this is very, very hard to justify over simply using Life Orb, as thanks to Reuniclus' Psychic typing, low speed and the fact that it's going to be locked on one attack, it's very easy to defeat. Alas, if it get locked on a Psychic-type move, Tyranitar and Scizor can take even more advantage of this to outspeed and either OHKO him or Pursuit him. Other Reuniclus can at least get around the two with good prediction skills, but this Reuniclus cannot even do that.Here's a set that I don't see too often, which is odd considering Reuniclus' ability and stat layout. I wonder why...
Reuniclus @ Choice Specs
Modest
Magic Guard
252 Sp Attack/252 HP/4 Def
Psychic/Psyshock
Focus Blast
Shadow Ball/HP Fire
Trick
Reuniclus can do some damage with this set. The choice between Psyshock and Psychic is up to you, but both are STAB, and even though they do have bad coverage, they hit hard on anything that doesn't resist. The remaining coverage moves provide, well, coverage, while Trick allows for Reuniclus to cripple things that would otherwise take attacks easily.
Reuniclus has no problems switching in and out of a fight, thanks to Magic Guard, and its stats allow it to deal real damage while tanking a hit or two.
Anyway, my favorite set is the CM set, which I've used on the past on sandstorm teams, before Genesect was introduced:
Reuniclus (F) @ Life Orb / Leftovers
Trait: Magic Guard
EVs: 252 HP / 252 Def / 4 Spd
Bold Nature (+Def, -Atk)
- Calm Mind
- Psyshock / Psychic
- Focus Blast
- Recover
Life Orb takes advantage of Magic Guard, and is useful when Reuniclus needs to attack right off the bat when you don't have sufficient boosts. Leftovers is also good because it boosts Reuniclus' survivability quite a bit.
Psyshock defeats the pink blobs much more easily and lets Reuniclus win Calm Mind wars against anything not named Jirachi. However, Psychic gets a harder hit on physically based threats such as Hippowdon and Slowbro. Focus Blast is the best coverage move that Reuniclus have. While Psychic-types resist both of Reuniclus' moves, there are some Psychic-types on OU that take neutral damage from Focus Blast, and with some boosts, Reuniclus can defeat them regardless. Other things like Hidden Power Fire and Shadow Ball aren't recommended. The former leaves Reuniclus vulnerable to Tyranitar and any other Dark-type not weak to Fire, not to mention Heatran. The latter leaves Reuniclus walled by any Steel-type not neutral to Shadow Ball or Psychic-type STAB.
I prefer Life Orb or Leftovers as items because their benefits are much more notable than being capable of defeating Breloom. Also, Reuniclus can simply switch on a predicted status move or Toxic Spikes if it wants to become immune to status. I also don't like Hidden Power Fire as a coverage move because of the reasons explained above. It's a shame that CM Reuniclus suffers from 4MSS, because Hidden Power Fire and Shadow Ball would be great coverage moves alongside Focus Blast and a Psychic-type STAB, but with only 2 rooms for coverage, Focus Blast is the best coverage move that can be run and its coverage is too hard to pass up.
As a last note, Hidden Power Fighting can be used if you really dislike missing with Focus Blast, but it doesn't have nearly as much power as Focus Blast, and can't OHKO/2HKO most targets of Focus Blast with either prior damage, hazards or some extra boosts.
