I plan on picking them up as I identify them. Some of the non-tcg cards have interesting art. I started collecting stickers as an offshoot of chasing the non-tcg cards.
The non-tcg identification thread here was a big help, particularly in identifying the Top cards.
I also used the Gardevoir masterlist under the PSA registry. That’s how I identified the Lenticular Panini action card; the one below the die-cut Gardevoir. I did note that the PSA registry doesn’t have the foil parallel of the Topps advanced card and the Die-cut insert.
On a side note, here’s a couple more items from my collection.
These are the Ensky Bromide cards. I believe they come with a pack of gum. They measure 8.1 x 11.9 cm. I found a picture of the set online, it looks like I’m missing the Mega Gardevoir without Diantha.
I also talked about the Lotte stickers earlier. Here is one I own.
