Each Play Booster contains 14 Magic: The Gathering cards and 1 Token/Ad card, Helper card, or Art card
But, when it comes to assessing the value of these cards, it's not always about their power or which card sees the most use in player decks
Eight lands in play is the break-even point where you can cast this for free, though you could always run it out earlier, hope it sticks around for a turn cycle, and untap with something like 10 to 12 mana from lands alone

As artifact tokens, theres a lot of use they can have beyond their own effects as well
