Name: Zoroark
Stats: 80 / 104 / 68 / 104 / 68 / 106 (530)
Typing:
Abilities: Illusion
Illusion: Displays the same HP and status conditions as the Pokemon being copied until the Illusion is broken.
Movepool Changes(if any): +Air Slash, Aqua Tail, Close Combat, Earthquake, Energy Ball, Fire Blast, Ice Punch,
Night Daze, Psychic Fangs, Stone Edge, Thunderbolt
Night Daze: 55 BP Special Ghost type Fake Out clone.
How does this fulfill the concept?: While it has weaker offenses aside from Speed, it also has much more defensive utility and a majorly expanded movepool to let it copy a greater variety of teammates. Night Daze is very cool for picking off weakened foes.
Name: Rotom-Frost

/
Abilities: Levitate, Download
Movepool Changes(if any): +Freeze-Dry, Ice Beam, -Will-O-Wisp
How does this fulfill the concept?: With its abilities, stats and typing, Rotom-Frost abuses BoltBeam primarily by being a Scarfer. Aside from this though, Special walls can give it trouble, even with Download.
Name: Mothim
Stats: 66 / 114 / 61 / 105 / 60 / 114 (524 BST)

Abilities: Tinted Lens, Infiltrator
Movepool Changes(if any): +Earth Power, Focus Blast,
Fly, Hurricane
Fly: No charge turn, 100% accurate.
How does this fulfill the concept?: Those Bug and Flying STABs are gonna hurt with those offenses and Tinted Lens! Its crappy bulk and Rocks weakness definitely chips down its longevity though. You could run Infiltrator to mitigate that somewhat, but that sacrifices your main source of power.
Speaking of which, I think people are misinterpreting the restrictions for Mothim. I merely stated you cannot lower Mothim's offenses below what they are in vanilla, not that they have to stay the same as vanilla. Unless that was a conscious decision, in which case forget I said this, move along
