>>32795383This reminds me I managed to wreck havoc in doubles for a while, time ago, with a Regigigas combo gimmick.
Regigigas with Misty Seed running Power-Up Punch, Return, Drain Punch and Fire/Ice Punch paired with Hawlucha with Unburden running Entrainment and Tapu Fini.
First turn Regi goes for P-U Punch while Hawlucha passes him Entrainment. Second turn I switch Hawlucha (which was most likely dead, to be honest) for Tapu Fini, whose Misty Surge triggers the Misty Seed, triggering both Unburden and the Sp. Def. buff, as well as making Regigigas immune to statuses for 5 turns. Rest of the team was Comfey to babysit Regigigas and other stuff that covered its weaknesses.
95% of the battles were over as soon as the strategy was set in motion. Fun times.
