Hopefully, it's not a creature and now for two, you exiled something and gave nothing in return
Check current card prices on Scryfall or TCGPlayer, multiply each card's value by its probability of appearing in your pack, and sum the total
That means to optimize value, you want three creatures entering on average every turn
There are lots of great sellers out there though with genuine products, so make sure you do your research before you head out and spend your hard earned cash
