This Chandelure would destroy everything in trick room, because 109 speed or 105 speed or something like that would be triflingly slow compared to threats like Choice Scarf Terrakion or Hydreigon. But here is another set that I came up with so it would not be slow and is perfect essentially.
Its ability would double its Sp. Attack, but halve its defense and attack.
Chandelure Hp 55 Attack 55 Defense 75 Sp. Attack 150 Sp. Defense 80 Speed 150 Total 565
