QWERTY DITTO said:Nope you're misinformed. Maybe the person that told you meant that once you have 4 you can put those 4 into every deck you want, like 4 catcher and you can have 20 decks all with the same catcher. So you really only ever need 4 of a card. Also just a word of advise that I personally like to do is: trade your packs for the things you need, like keldeo EX= roughly 8 packs, catcher= roughly 3 packs, etc. I like to do this because in 3 packs it is very unlikely to pull a catcher.
dmaster said:Just a heads up that there is a searching function in the trade boards on PTCGO so you can figure out how much things are going for.
A quick search and I found Promo going for 4/5, Regular going for 7, and FA going for 10.
dmaster out.
