It's been made quite obvious that Regigigas doesn't have a place in the Standard (OU) Metagame and certainly not Ubers. So we have lug his his load, far past the realms of balanced play, to the Double Battles Metagame.
Double Battling, arguably the most imbalanced metagame, has undergone improvements from it's breakout in Advance. For one thing, 2 pokemon using Explosion can only kill 2 pokemon as opposed to 4. A new move (Feint) can hit protect-abusers. (Though it does have a pathetic Base 40 power) and Sunny Day/Rain Danceteams got a boon in Heat and Damp Rock.
Now, unleashing 3 Combinations of Win for Regigigas:
First and foremost:
REGIGIGAS
Nature - Adamant / Jolly
EVs - 252 Atk / 252 Speed
Item - Leftovers / Lum Berry / Expert Belt / Chople Berry
Moveset
- Return
- Thunder Punch
- Ice Punch
- Earthquake / Brick Break
This set looks remarkably similiar to one of a tough, yellow yeti. That's right it's basically Electivire's "It's Super Effective!" set for Regigigas. Return for STAB, BoltBeam punches give amazing type coverage, but the choice between Brick Break and Earthquake both hit the same things, but Brick Break has the added advantage in breaking screens, used more often in Doubles.
Onto the Combos:
GRUMPIG
Nature - Timid
EVs - 252 HP / 20 SpD / 236 Spe
Item - Leftovers / Choice Scarf / Choice Specs
Ability - Thick Fat
Moveset
- Skill Swap
- Charge Beam
- Trick
- Psychic / Shadow Ball / Energy ball
The most offensive of the combinations. Psychic murders Weezing's that come in and try to Wisp Regigigas, whilst Shadow Ball will do similiar things to Dusknoir. Energy ball is for Bulky Grounds that shrug off Ice Punch. Not to mention that Grass/Electric makes for good type coverage.
Trick can screw over anything defensive that tries to block your path and Charge Beam is to kill the ever-present Tauntrados that wants to lower Regi's attack and taunt the Piggy before it can Skill Swap.
Whilst it is the most offensive skill-swapper, from these three, it ironically gives Regigigas a very nice defensive boost. The plague of normal typing is the lack of resistances and SE Coverage. This is partly remedied through Grumpig's Thick Fat, halving the damage from Fire and Ice attacks.
SLOWBRO
Nature - Bold
EVs - 212 HP / 252 Def / 40 SpAtk
Item - Leftovers
Ability - Own Tempo
Moveset
- Skill Swap
- Swagger
- Thunderbolt
- Psychic / Grass Knot
This set is designed to make Regigigas into a full-blown powerhouse. T-bolt for Tauntrados (Mentioned above), Psychic to hit Weezings harder and for STAB, Grass Knot to end those Swamperts that can Roar away Regigigas.
This set runs better with a Jolly Regigigas. The basic strategy here runs over 2 turns. After you Skill Swap "Own Tempo" to Regigigas, its Attack and Speed stats will revert back to 460 and 299, respectively (419 and 328, if Jolly). From here, Swagger Regigigas for a +2 Atk boost, without any confusion. The speed drop on Slowbro, won't matter as much as it would on Mr Mime or Grumpig.
SLOWBRO
Nature - Timid
EVs - 252 HP / 136 SpD / 120 Speed
Item - Leftovers
Ability - Soundproof
Moveset
- Skill Swap
- Hypnosis / Thunderbolt / Psychic
- Encore
- Reflect / Light Screen / Teeter Dance
Mr. Mime got a few nice boosts this generation, especially in the realms of double-battling. Screen support is always nice, allowing the already Bulky Regigigas to tank hits even better. Though with a little luck, Teeter Dance can prevent you from getting hit at all.
Encore helps Mr. Mime setup, forcing them to redo a move (Stat-ups, anyone?) or at least forcing a switch. Hypnosis can take something out straight away, though Thunderbolt is the reliable Gyarados killer. Psychic for STAB and Weezing.
Soundproof removes alot of Regigigas's counters and Reflect just helps that process to. Swampert isn't hit for SE on any of Regigigas's attacks and can simply roar him away, but Mr Mime's sound proof remedies that problem. Reflect can even tone down those STAB Earthquakes. Skarmory won't dare whirlwind with the threat of T-bolt and T-punch.
OTHER OPTIONS:
Gengar and Azelf get a mention to hit on the Special side of the Spectrum, whilst Regigigas beats down on the physical. Other levitating psychics like Bronzong and Claydol work too, offering screen support similiar to Mr Mime. In a similiar sense, Mesprit and Uxie can give Regigigas levitate, but offer little else.
COUNTERS:
When constructing this Topic, i thought of Regigigas as a suped-up Electivire. All it's counters were Regigigas's too. So Weezing, Cresselia, Swampert (And other Bulky Grounds) were thrown into the mix. Next, i realized that the Skill-Swappers were basically acting as BP Ninjasks, so similiar counters would apply too. Phazers and Taunters in particular.
So, from these, the most common Defensive threats were:
- Gyarados
- Weezing
- Cresselia
- Swampert
As you may have noticed, i've payed special attention to these, in Regigigas's team mates. Also, whilst Regigigas is Bulky it won't survive Close Combats from MixApe or Lucario, so threats like those were "managed" to a lesser degree. Chople Berry can save you once, and allow you end them soon afterwards.
Not to mention that all Skill-Swappers have so far been Psychic which hits Poison and Fighting, 2 types not hit for SE by Regigigas.
