I had the same problem but finall got a Maha. I got another from the EX trader too
Fun fact: i designed the first maha deck ever to be used in a national tournament. It is too bad i missed the event. I would really love to drop a few of these in game again. Do you have any odea how powerful one of these gets with 3 mage powers and a Yami field spell and you have a massive 9,250 atk on just one card. Of course with the usual 5 spell and trap slots I can take that to over 13,000.
