The symbol for cards was updated, so Organized Play cards should use the new symbol, with the older Promo symbol mostly used for cards at promotional events
The Commander Decks have revealed a ton of new cards in a similar vein that have great mechanical nods to their respective gamessome of my favorites include Zack Fair in FFVII s, which lets you essentially replicate Cloud swiping Zacks identity after his death, or Champions from Beyond in FFXIV s, a very nifty nod to the MMORPGs party finder mechanic (and one of the coolest moments in its expansion Shadowbringers )
Pick up Disney Lorcana: The First Chapter booster packs to customize your current deck or perhaps build an entirely new one
They each offer a collection of items aimed at specific ways to play on and enjoy Arena
This deck is an overall good learning tool
Value cards from this deck include Gandalf, White Rider, Aragorn and Arwen, Wed, Galadriel, Gift-Giver, and Bilbo's Ring, cards that see some play in Commander and can be interesting to build around
