Go get 2 accounts, have them both have the same attack, strength, hitpoints. One have 15 defense and the other have 1. Normal DDS to Dscim, no move.
Then sit there for hours on end and stake. Since the the 15 defense account will "supposedly" have 7.7-9.3% odds, you'll have to X. Just do a very miniscule X, such as 1.05. Maybe even 1.03. But that shouldn't matter cause you've got pretty good odds cause of your 15 defense.
Then come back and tell me when you're cleaned.
