Starting off right at the beginning. This one is not confirmed, but my personal opinion. I noticed this by looking at a graded Wave 1 Foil. The foil pattern is different between the 2 Waves. Here are the two guides from the introduction post that will help you guide your way.
“Distinguishing Final Fantasy TCG Opus 1 Wave 1 from Future Waves”
“Differences in Opus I Wave 1 Printing vs Later Waves”
If you look closely, you can tell that the colors on the cards are a little different. The Wave 1 card looks a little dull compared to Wave 2 which is more vibrant.
Wave 1 is on the left, and Wave 2 is on the right.
First off, I noticed that the whole card is moved up, not just the Crystal. If you take a look at Auron’s boot there is more showing than what is on the Wave 2 card.
Something else I also noticed, but is not consistent on Wave 2 cards. Could be the difference between Wave 2 and Wave 3. There is a little, let’s call it a, blob on the left side of the card. Could just be a printing error, but it is something I noticed when I was studying the cards.
