There is not so much different between the normal art and the parallel art of Dexmon, same theme same color even though 2 different artists drew them.
The Alphamon: Ouryuken mode, the last card revealed, have brought my disappointment to the lowest. I am not the fan of the art that the Digimon weapon takes almost half space of the art. Not only that, this art is not classic, not elegant and underwhelming.
Even though these arts are not my favourite but they are secret rare, and they are also the hidden potential in BT9 meta that may bring us many creative decks, especially Dexmon. Their prices may not be around $100 or something, and SEC AA is somehow easier to pull compared to some other SR AA cards, so they are still affordable.
