Talk:(Retrieval) Perfected Battle Dragon/@comment-152.226.7.201-20121128044339

I assume it's not simply 20 cards. Think like the Whimsical Tempest Queen where the final evolution requires a total of 16 base cards to get the perfect max stats, and it only have 5 stages. Since Battle Dragon require 10 cards to get to the final form, you can probably imagine that it needs 2^10 cards, which is 1024.

I could still be wrong though.
