Ok i have a kerrozin cr but its max xp.... why is it more valuable if its 0xp i just dont understand.... if the card isnt better at say 3* or 4* for slot filling which isnt even elo legal anymore, why is it worth less at its most efficient state? IE why i mine worth less than random joes at 0xp?
Really isn't the right place to discuss, but it's because 0xp cards are presumed to be in "mint" condition. Meaning they were never used in a match yet. Same reason why mint edition comic books are worth more than old, pre-loved ones. You can turn an 0xp card into a full one, but you can't revert a max XP card back to 0xp.
It's kinda stupid, but that's the way the traders work.
