Most collectors cares about condition. Mox opal is a bad ass card too but barely worth the paper it is printed on when it is crumbled up like snot paper, as an example.
i beg to differ ive seen many a times that people have even preferred to get something much more valuable than a mox opal in bad condition i understand that its mostly because the more banged up it is the lower the overall value personally i dont really mind the condition of cards because i mostly dont pay cash for a single card anyway im more of a player than a collector so as long as i can play it ill tradefor it.
