Mega Metagross Movesets & Competitive Sets

Prankster Mega Metagross is an effective Substitute + Baton Pass user due to its good defensive typing into most Wonder Guard and -ate users, decent overall bulk, and Prankster + Dark Void effortlessly giving it free turns for setup. Dark Void and Coil synergize well because Coil boosting accuracy remedies Dark Void's accuracy problems. Dark Void allows Mega Metagross to disrupt non-Magic Bounce switch-ins thanks to priority from Prankster and often lets it Baton Pass both a Substitute and Coil boosts to a teammate. Likewise, Taunt and Minimize work well together because Taunt disables Prankster Giratina’s moves, allowing Mega Metagross to rack up evasion boosts, as most opposing attacks either miss or fail to break Substitute. Substitute is essential to Mega Metagross's purpose, as offensive teammates enjoy being able to take a hit from most revenge killers while attempting to set up and sweep. Leftovers keeps Mega Metagross healthy and allows it to use Substitute more frequently over the course of the game; in the majority of games, it is sufficient recovery for Mega Metagross to function effectively. Prankster Mega Metagross differentiates itself from Wonder Guard Substitute + Baton Pass users by preventing Prankster Giratina from immediately forcing it out with Encore or Spore. A specially defensive EV spread is used so Mega Metagross's Substitute can take a hit from unboosted Xerneas's Moonblast and Sky Plate Mega Rayquaza's Oblivion Wing and so it can more effectively tank Boomburst from users like Pixilate Mega Diancie and Arceus. Setup Mold Breaker users appreciate Mega Metagross's ability to pass them Substitutes and Coil or evasion boosts immensely. In return, they can threaten Magic Bounce users that can come in on Mega Metagross and bounce back Dark Void or Taunt. Dark Void + Oblivion Wing Mega Rayquaza in particular is a great teammate, as it appreciates both Coil's accuracy increase allowing it to use Dark Void against foes with impunity and Minimize boosts putting Prankster Giratina in a bind due to Oblivion Wing offsetting damage from Curse, therefore forcing it to use Encore—which can miss—instead. Bulkier offensive Pokemon, like Mold Breaker Primal Groudon, work well with both Coil and Minimize Mega Metagross because Defense boosts from Coil make them harder to revenge kill, while Minimize boosts allow them to fish for misses against Prankster Giratina's Encore and attacks from revenge killers. Magic Bounce Giratina excellently Imposter-proofs Mega Metagross, though the need for robust revenge killers due to forgoing Prankster Giratina means it is difficult to fit. Substitute + Baton Pass Wonder Guard users that threaten Giratina, namely Xerneas, Mega Gardevoir, and Mega Gengar, are also valuable teammates due to their ability to switch into Huge Power or Protean-boosted coverage moves that Mega Metagross may defensively struggle with. Prankster Giratina, support Wonder Guard users, and revenge killers are essential due to their ability to switch into offensive Mold Breaker users, remove entry hazards and act as clerics, and offensively check most opposing attackers, respectively.
