Okay, so here's what I have for my team of YOU-killers:
Typhlosion - Flame Wheel, Thunder Punch, Earthquake, Hidden Power (Ice)
Aggron - Iron Tail, Double Edge (Rock Head ability), Magnitude, Mirror Coat
Gardevoir - Psybeam, Shadow Ball, Shock Wave, Future Sight
Staraptor - Fly, Close Combat, Roost, Quick Attack
It's all I have so far. It's hard to find Pokemon I like.
My gym requires some thinking. Four rooms, each representing each of my Pokemon's types, each one with a puzzle. Each room has two trainers you can fight as well (they can't interfere with your puzzles, so don't worry).
Fire - you must have only specific torches lit, but each one torch you light or put out will affect the others.
Steel/Rock - You must plant boulders on to steel plates. Basically, it's a sliding puzzle (Strength required). The boulders and the plates are not directly aligned and you must figure out how they go where.
Psychic - You must move your doppelganger, which moves in accordance with you, onto a switch that opens the door. The catch is that the room is a maze with no dead ends. Good luck with that.
Normal/Flying - There are invisible paths over a pit you must somehow navigate. Three switches open the final door to me. (Don't worry; a secret passage opens if you win. If.
Incidentally, why did the Recaptcha bot filter ask me to type 10 to the negative thirty-third power in exponential form? Is it trying to make me break my keyboard?
