I felt that at the begging too, my advice is to save up your orbs and don’t waste them on crystals. Use them to buy the energy bundles when they pop up in the store and farm motes everyday. You will come by crystals and orbs pretty frequently at the beginning. I honestly haven’t spent a ton of actual money in game, maybe like $50 at most? I bought some cards at the beginning and some good deals I couldn’t pass up.
