Origin Form Dialga VSTAR deck that hits hard for prizes, supported by Metang's ability which can dig 4 cards for metal energy. Note this isn't that much of a VSTAR deck but a metal box. Buddy buddy poffin and artazon also helps get the Beldum on the bench. Iron Hands to attack single-prizers. Zamazenta and Metagross as a side attacker (metagross can also serve as a draw 3 engine with Chiphermaniac's Codebreaking with Trekking Shoes and possibly even be a strong attacker). 1 copy of reversal energy in case you're behind on prizes and you need to catch up.
