Try to get both Legendary 100% and Gold Foil 100% that way you may get a lot of profits.
I follow a simple rule where if I get two Epic Gold Foil Cards I already make my money back and the rest I keep as profit. This time I got two GF Brownies plus a lot of other cards but the Brownies will make me my Money back and I buy another Potion from that.
