I got charge card in about 3 games with my Glass Cleaner, I waited until the guard got to half court then tried to get him after he crossed half court. I also got a couple off of screens that the cpu set, I would anticipate the direction he would go and it worked out. It is not that hard.
So you got the corner specialist badge finally? what was the trick...I am over 300 corner 3s now and 42 badges and still not that one.
