Which version do you have?

If you just want the card, buy the Standard version for $0. The Reverse Holo version at $2 offers a slight visual upgrade, but in this case, the difference is minimal. Since the price gap is small, paying the extra $2 for the Reverse Holo is a minor indulgence for collectors who prefer a slightly more premium look. For budget-conscious buyers, stick to the Standard.
