Building Process
Whenever anyone says the name "Reuniclus", most players will immediately think "Trick Room". That's exactly my thought process behind this team. Now, this is my first Trick Room team, so it probably isn't that great, but here goes nothing. I started with the basic Reuniclus set, the offensive Trick Room. Then to go along with the required core, I had to go with Mega Heracross. Rock Blast, Pin Missile, and Bullet Seed are used to abuse MHeracross' ability, Skill Link. Close Combat is in for the fourth moveslot to decimate whatever doesn't resist it.
I figured that for this team I needed at least one more TR setter, but decided to go with two, Dusclops and Porygon2. Dusclops seemed like an obvious choice, due to its insane bulk when holding an Eviolite. The set is mainly used to cripple the opponent's team, trapping them with Infestation, then either using Pain Split for recovery or burning the opposing mon. Porygon2 was added as the other TR setter also because of its bulk with Eviolite. I realized that my TR setters needed to be able to tank a hit, since TR has a negative priority. The rest of the set is Porygon2's standard offensive set, with BoltBeam coverage and Tri-Attack as STAB and a way inflict status and deal damage.
For the final two, I just looked for bulky, slow pokemon. Tyranitar is bulky on the special side and is a strong physical attacker. His standard CB set seemed like a good choice, and I was sure to invest some EVs into SpD. The last mon is Slowbro, who I thought was a good complement to Tyranitar, since Slowbro is bulky on the physical side and is a strong special attacker. Scald is for passing burns, Psychic for STAB, Ice Beam for coverage, and Toxic to pass yet another status.
