Brave Neos is Blue-Eyes Solid all over again, a meh UR in an EX deck.
Connector is the only interesting card so far, but even then, she's not THAT game-changing. So there's definitely going to be something else we don't know yet that will be the real attraction point of the deck. I think it's gonna be Neo-Spacian Ground Mole.
I'd be extremely surprised if there were any other new cards here. It's kinda random to have most but not all the new cards listed. The rest of the deck is probably multiple copies and some existing cards, there's nothing else new to see. Kinda wanted to see Cosmo Neos here as a Miracle Contact target.
Cosmo Neos seems nice, but since that his original summoning condition (I mean without using Miracle Contact) requires 4 monsters to be on the field, I doubt Cosmo Neos is coming to DL ever.
I mean, new cards are known only because they are new. Swarm of Scarabs and Human-Wave Tactics appeared in a box, but the datamining for their box did not include them, because the cards are already in the game, used by NPCs.
I can't remember if it was already, but since ground mole popped up again, I guess it could be possible for it to be in the deck. Or maybe it is just for an AI in the tag duel or some other event.
Brave Neos IS meh, what's strong is Neos Fusion. Brave Neos just happens be really good when paired with Neos Fusion, so I guarantee it won't be as abused as now if we only have regular Poly to summon it, and no Neos Fusion.
