While Reuniclus may seem like a strange choice to suspect as it has been in the meta since its inception, Reuniclus has actually been brought up at several different points throughout XY and ORAS RU as a potential suspect, but the timing was never right as tier shifts or some other threat popping up always got in the way. The set that has, at times, been worthy of a suspect test is the Calm Mind set, which is extremely profficient at dismantling defensive teams once the dedicated counter to reuniclus has been removed or weakened (and sometimes even without this). Often times the counters that defensive teams carry to deal with Reuniclus, such as Drapion and Skuntank, are easily taken care of by Dugtrio. With Doublade's exit from the tier, Reuniclus doesn't really need to run Shadow Ball anymore, it can run Focus Blast to deal with Dark-types like Houndoom and the aforementioned Drapion and Skuntank, or if you are concerned with Spiritomb, Reuniclus can easily get away with running Signal Beam, which hits Spiritomb and the other Dark-types neutrally, at the small cost of having trouble with Steel-types that can also set up. Magic Gaurd is what makes Reuniclus so potent, as it cannot be dealt with by status, unlike other set up sweepers, it also makes it extremely resiliant, as it doesn't take damage from hazards. Reuniclus still serves as a good win condition against offensively oriented teams, as barring strong Dark-type Physical attackers (and Houndoom), and a select few very powerful wall breakers, Reuniclus becomes basically unpenetrable after a few calm mind boosts. OTR is also an option that can take advantage of the fact that Reuniclus isn't often thought of as hitting hard right off the bat, but OTR flips speed on its head and allows Reuniclus to easily clean faster teams, given its extremely high Special Attack and recoil-less Life Orb boost. Because of the recent tier shifts, as well as its long standing position as one of the best and threatening bulky set up sweepers in the tier, Reuniclus has been deemed worthy of a suspect test.
