For everyone wondering why it's super rare; Rex said it's a super rare monster in the anime and in battle city tournament it was considered his rarest card. It's a useless card, but they are just staying loyal to the show
I would ALWAYS run Red Eyes over this card. Both are normal 7 star dragon monsters, but red eyes has slightly hiogher atk and has more summoning options, like Red Eyes B. Chick. Only upside to this card is it's defense, but usually when tributing you're more focused on the atk.
Dont forget all the fusions u can do with this card...i used 3 REBD against pegasus...and black meteor dragon and black skull dragon(2)..7000 pts..Yea this serpent is useless...ive got2 dragon chicks :D
