Once it's face-up, anytime you cast one of the two named creature cards, you can search your deck for the other, reveal it, put it into your hand, and shuffle your library
That means configurations like Amazons 6-pack Booster Bundle are the absolute most cost-effective way to hunt for the elusive Special Illustration Rare Eevee ex or the gold hyper-rares without paying for extra plastic fluff or giant premium collection boxes
This allows you to select the most useful of their cards and prevents them from being played against you
As mentioned above, it is a little harder to handle than Subtra, but in Mathmech, it is an excellent material that you want to stack 3 times, and a buff agent
Given that rarity, the card didnt surface in public for more than 20 years after it was awarded to Yamaguchi - with even pictures unavailable online - until it surfaced in July 2023
Nothing with Blue qualifies
