Some observant players may have noticed this problem: even if you have a very good character or lineup, you still appear relatively weak against Kryptonite players. What you may not know is that these players, known as "local tyrants", are likely to be using internal accounts, and currently the Battle Donkey Game Network only distributes about ten slots per day. For those who were able to grab a spot, it was undoubtedly very lucky. If you're also interested in an internal account, try your luck.
