I'm still new to the card game, well all the new sets and there's so many cards. I've mainly bought a lot of the D/P sets since i've came back to the ccg world. I plan on starting to play in local tournaments and attend GenCon Indy this year(My dream is to win it.) Now I was wondering what are some basic rules for building a deck like how many energies should go in a deck IE. Thanks for all your help!
