Crolegion: Prank Taunt and Milk Drink on a decently strong Dark mon. The main theme this mon has is moves with powerful secondary effects. STAB Wicked Torque, Dire Claw, and Triple Arrows make for a strong set of moves with some nasty secondary effects tacked on. You can run either of the aforementioned moves or Tailwind as your fourth slot. I certainly don't hate it.
Wizpole: No. Illusion is already a red flag, but it's absolutely unacceptable on a mon that has such high offensive stats. This even gets EdgeQuake and Fusion Bolt. And Guts, in case you really need the extra power, but Illusion is probably better because you never know if the mon you're facing can pull out a disgusting physical move instead of what you thought it would do.
Termtera: This thing would be solid as a specially leaning mixed attacker in Trick Room but really needs it to not get overwhelmed damagewise. It can throw out some significant damage thanks to Beads of Ruin, Giga Drain might help with sustainability somewhat, and it gets very solid coverage even without factoring in Judgment (Earth Power, Giga Drain, Overdrive, CC or Fighting Judgment), but most physical mons can easily overwhelm it.
Stunecko: This would be a Pokemon with not much going for it if it weren't for Leech Seed and Lumina Crash. Its coverage isn't particularly good, but it can at least break some stuff with Lumina Crash while sustaining itself. It gets Snipe Shot for Grounds. It doesn't have much for Steels, though. Overall a thoroughly average mon. Is it better than nothing, that's to be seen.
Hunttar: Orichalcum Pulse V-Create hits like a truck, even with that bad Attack stat by Roulettemons standards. This will probably run Band Dragon Darts V-Create Flip Turn, and maybe Wisp or Brave Bird. This is just a V-Create machine, and I respect it.
