I'm asking this because I bought a "Terrific Tepig Box" and it came with what they call a oversized card. So I was just curious can you use them in official matches? I thought that would be kind of funny if you could
The short answer is no.the large cards are promo cards and are rare cards that are limited edition so they often sell for alot on eBay,you can search it if you want.you can only play cards that fit in the outlines
Hope this helps!
