RE: Marowak!
The set comes out this November. There isn't much of a strategy behind it. Search out Stadiums via Honchkrow G, deal damage. problem is that you would need to play 8-10 stadium cards which is alot of space, plus if you happen to come up against Dialga G, they'll deafen lock you and shut the deck down (Not too hard to tech against)
A decent-ish card though.
