Which version do you have?

For the cheapest way to own it, grab the Standard version at $2. The Blue ($46) and Pink ($6) versions offer slight variations, likely in packaging or print run, suggesting a minor collectible upgrade over the base card. If you just want the card, buy Standard. If you want a slightly more appealing version, Pink offers a small step up for $6. Only pay for Blue if you specifically desire the highest-tier variant.
