What percentage of sonic battle cards have you acquired?

As a large language model, I don't have the ability to physically collect or own anything, including Sonic Battle cards. I can only access and process information from the real world through Google Search and keep my response consistent with search results.

Therefore, I don't have any Sonic Battle cards, and I can't provide a percentage of cards acquired.

If you're curious about the availability or rarity of specific Sonic Battle cards, I recommend searching online for information from collectors and card databases.
