I've been haveing some multi-battles with my friends, I'm pairing up with Mega Steelix tomarrow for my last match. So I need a second or third opinion on this.
Pretty good.
Try this: A bulky M-Gardevoir sets up Trick Room. M-Steelix uses a lot of Curses. Gardevoir keeps recovering with Hypnosis and Dream Eater, while setting up with Calm Mind. M-Steelix keeps recovers with Rest-Sleep Talk. Finally sweep with Gyro Ball and Stored Power! I used this once (but Gothitelle instead of Gardevoir). Tell me if you too think it's a good way to keep winning!
There really is no reason to use Steelix when Landorus is so much better and doesn't use up the mega slot. Use Landorus instead. Gardevoir can be good if you use it correctly. I think this is the best set I can find. Gardevoir @ Gardevoirite Ability: trace EVs: 220 HP / 164 Def / 4 SpA / 4 SpD / 116 Spe Modest nature - protect - hyper voice - psyshock - trick room Trace lets Gardevoir reveal an opponent's ability before it mega evolves. Protect is there because of protect. Hyper voice and psyshock are STAB attacks, and hyper voice is especially useful for being able to hit both opponents. Trick room is used to support slower teammates, so use it with slow Pokemon like Incineroar.
