I have a whole album of my favorite art I use for a lock screen.

My favorite has to be the rainbow rare Pikachu EX from Shining Revelry.

Also the full art Marill in the pond with the lily pads is one of my favorites too.

Mine is Spurt Fire Magcargo.

There are cards with awesome illustrations (e.g. rainbow rares), and others that can reliably win me games (e.g. Cyrus), but this card is what kept me going back to battles.

It doesn’t always hit, but when it does, it’s glorious.
