Unsure if this is inconvenient or not, but I will not include code from the generator because it does not use the memories.
Mega Silvally-Fairy
Ability: Speed Boost
HP: 95
Atk: 95 ---> 150 (55)
Def: 95 ---> 105 (10)
SpA: 95 ---> 150 (55)
SpD: 95 ---> 105 (10)
Spe: 95 ---> 65 (-30)
Weight: 120 kg
New Moves: Moonblast, Dazzling Gleam, Nasty Plot
Description: Silvally has almost no way to boost specially, neither is he a good offensive mon. Here, I do my best to make him as offensively good as possible, while not being completely broken. A very low base speed coupled with Speed Boost means he needs a couple turns to get going. But when he does, those base 150 attacking stats will hurt. With even attacking stats, You don't know how he'll hit. And with access to Nasty Plot, Swords Dance or Work Up, he can hit anywhere.
Mega Silvally-Dragon
Ability: Prankster
HP: 95
Atk: 95 ---> 105 (10)
Def: 95 ---> 150 (55)
SpA: 95 ---> 105 (10)
SpD: 95 ---> 150 (55)
Spe: 95 ---> 65 (-30)
Weight: 120 kg
New Moves: Will-O-Wisp, Recover, Dragon Tail
Description: Since Dragon is the opposite of Fairy here, I designed Silvally here to be a wall. Huge defenses, recovery, Prankster, Dragon Tail and access to T-Wave, Toxic and WoW makes this sound like a monster. But inability to use any status against Dark types runs it low. New megas such as Mightyena and Liepard completely hard wall him though. If you can cover his weaknesses though, he'll sure stall his way through.
Mega Silvally-Dark
Ability: Dark Aura
HP: 95
Atk: 95 ---> 144 (49)
Def: 95 ---> 118 (23)
SpA: 95 ---> 65 (-30)
SpD: 95 ---> 118 (23)
Spe: 95 ---> 130 (35)
Weight: 120 kg
New Moves: Knock Off, Sucker Punch, Taunt
Description: This is being paired with Silvally-Ghost, so scroll down there.
Mega Silvally-Ghost
Ability: Ghost Aura (Dark/Fairy Aura effects, but it only applies to the Ghost type. Effects include 33% boost and it stops working once Aura Break or another Aura enters the field.)
HP: 95
Atk: 95 ---> 144 (49)
Def: 95 ---> 118 (23)
SpA: 95 ---> 65 (-30)
SpD: 95 ---> 118 (23)
Spe: 95 ---> 130 (35)
Weight: 120 kg
New Moves: Shadow Sneak, Spirit Shackle, Destiny Bond
Description: This is being paired with Silvally-Dark. I have no reason to keep them together, so go ahead and vote them separately if you wish. Also, Silvally-Ghost cannot learn Pursuit, Crunch, or Bite. This is to balance the two. The idea is they're the same Pokemon, but one specializes in Ghost moves and the other in Dark moves. One cannot be both. They will have the same stats, but differences in movepools and abilities. Also type priority, if that matters.
