The only issue with the deck is knock out power. The best metal decks I've ever come across run dialga. I think the M sizor/dialga/Jirachi Promo/Bronzong route would go over fairly well. Plus the use of the stadium card and a muscle band creates defense and hits the 170 mark. In metal decks, AZ and Max Potion has always worked. A lot of metal decks, in the past, never really ran keldeo/Zorark/float, they just paid the retreat cost, put bronzong in the active with float stone and charged the next pokemon up. Then they would max potion/AZ the damaged pokemon. It was how they got around the energy disruption.
It was also reason that Garbador/Siemitoad became big and Siemitoad/Slurpuf started to fade out. Siemitoad/Slurpuf could not disrupt the energy flow fast enough -- and with steal shelter, it gave the deck even more problems. Players don't like problems. Garbador shuts the deck down. And soon after that, everybody flocked to Siesmitoad/Crobat because those bronzongs were easy targets. Manetric decks will be a bad match up for this deck. That is why Dialga is needed for the knock out power.
For standard, I think dialga will work well into the deck as the power house hitter. Jirachi Promo and M sizor will be the annoyances. I think double down on hammers team flare grunts and Xersoics will be something that players will flock too with the release of the deck. However, competitively speaking, players usually can find ways around it when they are not item locked. Lucario/Hammers is a good example of players working their way around the disruption. It hasn't had any good consistent showings at cities yet.
