the best option is beta but they cost more, you can get set a goal of what level you want your deck, so for example level 3, then slowly buy your favorite 3 splinters summoners only.If you can combine a reward card to level 3 anything beyond that you don't need so sell those cards to buy the summoners. Ill look at making one of my up coming post all about this. Remember a limited strong deck is much better than a vast weaker deck
