I need help with my rookie deck

[Repyboy]

I started with Rayquaza GX and wanted a deck suggestion to do with it.

 

I do not have many gold to buy booster ;---;

I'm going to guess you talking about the online game.

 

Don't buy Boosters. Don't worth the cost or the reward. 200 coins for a nothing good guaranteed inside.

 

Buy Theme decks, starting by last ones or choosing by its trainers. Check this thread > http://forums.pokemontcg.com/topic/70032-theme-decks/?do=findComment&comment=620789

 

Every theme deck it's 500 coins for around 40 "useful" cards (and some energies) to fill your collection and get some staple trainer cards.

 

Also, just playing daily, you can get some hundred coins. I suggest you play Trainer challenge until getting 500 coins, then get some of the last Theme and play Theme VS for a while because, if you want to make a Ray GX deck, you need 3 or 4 copies of it. Playing one copy of a card means is useful but not important so, can help you in some specific games but it's not the core of your strategy.  Anyway, for the future and in Expanded, you can check the net for Rayquaza GX/Ho-Oh GX deck.
