The lack of VMAX decks for Melmetal in standard is so low disturbing taken from darth vaders "Lack of Faith" This deck follows rotation format
Metang is great for energy digging. VMAX only needs 5 energy like Dialga VMAX but the 280 + 30 can hit hard if needed
(ACESPEC Legacy Energy coming in Crimson Haze later allows a VMAX to only give up 2 prizes instead of one)
Update: the deck new Maximum Belt ACESPEC can help unlock the magic 330 to ko a bulky EX's like Charizard and just turn it into 15 energies
Don't know about slotting a Mist Energy to protect against Frenzied Gouging
