No, I don't think it is.
The new filagree seems to differentiate Reward Treasure cards and Promo cards from the Treasure Cards you find in packs.
Nice!
Yeah, I saw an updated filigree on the Poog promo card last night.
I love the change in borders as cards become more rare. It's confusing, though, and even moreso when it changes. Would love to just see the rarity written somewhere on the card as well as the border changes. May just be me though.
Thanks for the answers though I can't recall being rewarded with Samisen on the screenshot in my post Anyway, I also would love to see card rarity section in the Rules. Would be great.
