I feel like trying something new, so here's my attempt at a Trick Room based team for the Battle Tower.
Gardevoir @ Leftovers
Trait: Trace
Relaxed Nature
EV’s: 172 HP/252 Def/84 Sp.Def
- Psychic
- Thunderbolt
- Trick Room
- Wish
Gardevoir is my Trick Roomer. It sets up the Trick Room (obviously), then it uses Wish, and the Pokemon I switch in will be recovered by Wish if it is unfortunate enough to take damage.
Rhyperior @ Muscle Band
Trait: Solid Rock
Brave Nature
EV’s: 252 Atk/252 HP/6 Sp.Def
- Stone Edge
- Megahorn
- Earthquake
- Ice Fang
I have Muscle Band instead of Choice Band so Rhyperior has more freedom with its attacking. Also, Ice Fang is used over Avalanche so I don't go last, even with Trick Room set up.
Heatran @ Macho Brace
Trait: Flash Fire
Quiet Nature
EV’s: 252 Sp.Atk/200 HP/58 Def
- Flamethrower
- Earth Power
- Dragon Pulse
- Dark Pulse
Macho Brace is on Heatran to completely slow it down so it can't be outsped during the effects of Trick Room.
