Which is rarer Blue eyes white dragon or red eyes black dragon?

Answer 1

It depends if you are just throwing it into a deck then Stardust Dragon is usually the better choice. However Blue eye's White Dragon is better in certain decks that revolve around his element/type and has a ridicules amount of support cards like Kaibaman, Paladin of the white dragon and White Stone of Legend it also has way more advanced forms like Blue eye's Ultimate Dragon and Blue eye's Shining Dragon and since he is a normal monster it makes ancient rules a very easy way to summon him so overall I would say Blue eye's White Dragon is the better of the two card's if you plan on building you're deck around one of them and Stardust Dragon is better if you just want to throw one of them in a deck built around something else.

Answer 2

Both cards were printed in multiple rarities, including Ultra Rare. The answer to this question cannot be determined with the information provided. To compare rarities of cards, you can look at the lettering, the picture of the card itself, and sometimes the card trim (Gold Rare series). You can also compare by looking at the Card Identification code and seeing which booster pack they came in.
