You don't need Metang since Angry Slam only needs 1 M energy, unless you're trying to play around the tank build with Guard Claw.
Personally I'd run this Aggron like Zoroark VStar with Dodrios and Gengar/Damage Pumps.
Ngl I'm thinking of redoing my H-Zoroark VStar deck with Aggro as the main attacker and having like a 2-2 or 1-1 H-Zora VStar for the draw ability and extra attacker, looks very fun.
