Description: Regigigas, my favorite larger legendary! His ability is still as awful as always but there are ways to work with it, but rather than use skill swap in vgc/ doubles, or turn to stall tactics in singles/ smogon rules, I've tried out a set that utilizes some new items and moves in generation 6. To start, make sure that powerful physical and/or fighting types on the opponents team are crippled by trick room/ ailments or just flat out KO'ed, and switch Regigigas in. With an Assault vest equipped, regigigas obtains an obscene amount of sp bulk (110/110/110 defenses aren't shabby even without the vest) at the cost of his non-attacking moves (thus, his stalling power). But by taking advantage of gen 6's new move power up punch, Regigigas can raise his attack stat naturally and after two hits (which would put him at +2, or 2.0X attack), slow starts attack drop is effectively nullified. The fun begins however, when 5 turns do pass and regigigas returns to normal, then you have a +2 to +5 uber level Pokémon rampaging through an opponents team, which is quite the sight let me tell ya'... Façade can be used over return for Stab as façade allows regigigas to muscle past burns (since façade ignores the burns attack drop in gen 6) and a base 140 power (70 without an ailment, not counting stab on either) attack is surely gonna annihilate something should slow start end, though return obviously brings more power immediately. Drain punch is so Regigigas can heal himself while trying to sweep, while I understand that two fighting moves is terrible for coverage reasons, they both serve different purposes on Regigigas and must be accepted for this set to function at all. Finally, Knock off is for crushing ghost types as well as supporting the rest of your team should regigigas go down (a foe without an item is an easier foe to take down in the long run.). This set has flat out destroyed opponent teams for me in PU (which is where regigigas is currently) sometimes 6 to 0ing them without a single Pokemon of mine fainting! Although strong if allowed to set up, this set is weak to powerful physical attackers (especially fighting types), and while facade can combat burns, regigigas still hates ailments, as well as phazing, and ghost types who stop him from setting up his Power Up Punches. Overall though if you stop his counters and are mindful about opposing roar users, Regigigas just might surprise you and leave your opponent slack jawed!
