You can't use plane cards, oversized cards, or those giant cards that are sometimes given away as prizes or at conventions
None of these appear on a price-comparison screenshot
(This is the general rule, but there are cards in the tabletop version of the game that allow you to swap it around.) Here are the effects of all three Pokmon Tool cards in TCG Pocket: Lum Berry : At the end of each turn, if the Pokmon this card is attached to is affected by any special conditions, it recovers from all of them, and discard this card. You can use as many Pokmon Tool cards as you want per turn, but you can only use one Tool card per Pokmon
With the exception of the Kaladesh block, Vehicles have also played a supporting role in sets, so many players enjoyed getting to have a set where Vehicles could shine
Letting your opponent choose to discard whatever they want this is not very good, but with Treasure you can turn it into a better Thoughtseize, and thats pretty neat
From championship prizes to one-of-a-kind creations, these cards represent the pinnacle of Yu-Gi-Oh collecting
