Hello all! I have been having a bunch of fun playing with this Metagross deck, which I have slightly adjusted based on what I see locally/online. My biggest issue, however, is being unable to deal with Mega Lucarios or Single Prize decks. I can't find a way to OHKO a Mega Lucario without Heatran, which requires a lot of energy. Taking more than one turn to KO Mega Lucario can be very troublesome due to the constant retreating (Air Balloons and Switch) and Wally Compassions that undo my progress. With Single Prize decks, my Genesect is targeted frequently with Boss's Orders, leaving me at a huge disadvantage.

Is there any recommendations for how I should play against these matchups or what I should change from my deck?
