>>37396834I think it's a reference to XY. In Route 20, you could sometimes encounter a horde of 5 Trevenant, but there was a small chance that a single Sudowoodo would appear with them, pretending it was a Trevenant too.
>>37397244It can get very expensive if you try to collect them all, but if you set some limits for yourself, you should be fine.
Personally, I buy cards just for the art. I don't know how to play the TCG, but I just like looking at the art and collecting the cards, even though I know I'll never be able to get all of them.
