A Stealth Rock set that utilizes some things Copperajah got due to the DLC. Stealth Rock lets Copperajah setup a hazard that chips opposing Pokemon switching in. Heavy Slam is used for the Steel STAB since Copperajah with Heavy Metal makes this thing quite heavy. Copperajah can learn Knock Off now, which is useful for pressuring Pokemon even more. Copperajah getting rid of items such as Rocky Helmet from Pokemon such as Qwilfish and Sandaconda, as well as Heavy-Duty Boots from Pokemon who use them makes this metal elephant better than it was before. Protect allows Copperajah to scout the movesets of opposing Pokemon and gives it a free turn of Leftovers recovery. Copperajah gets Heat Crash back, so that move can be used for a coverage move against Pokemon such as Rotom-Mow, Decidueye, and Arboliva. Tera Dragon lets Copperajah resist Fire, Water, Grass, and Electric moves. Tera Water can be used to resist Fire moves without making it weak to Dragon moves. Tera Ghost can be used to turn Copperajah's Fighting weakness into an immunity.
Because Copperajah is one of those Pokemon where it has a massive HP but low defense stats, 252 Special Defense EVs are used to give Copperajah as much special bulk as possible. 76 Speed EVs allow Copperajah to outspeed Arboliva. 16 Attack EVs with Adamant Nature not only gives it a jump point, but it also allows Copperajah's Heat Crash to OHKO Rotom-Mow after taking Stealth Rock damage, which is useful if you use Heat Crash. The rest of the EVs are used in HP for bulk.
