Which version do you have?

If your goal is simply to own Dark Slowbro #28, buy the Standard version for $75. The 1st Edition, priced at $55, offers no tangible advantage in this case, as the price is lower, suggesting the premium is in perceived scarcity or collector preference rather than intrinsic value. For the budget-conscious collector, the Standard is fine. However, if you seek the lowest possible entry point, the 1st Edition is the cheaper purchase.
