First off, try to be a little more clear in what you are saying (writing?). If you are asking if it is possible to predetermine what cards you have in the battle than no. However, the cards in the battle are chosen from the cards in your deck (usually made up of 8 cards). Now, I'm assuming that you know how to build a deck, but to be safe, it is under the tab labeled Collection (On both the website and the app).
Looking back, my post sounds condescending, I didn't mean it this way.
