I'm confused by this statement. If you've got characters in the concealed area, don't you just shove them in the front row and say to hell with reinforcement?

As far as Injustice for All, I'm tempted to say it's trash, despite the fact I've been collecting them. I -can-, however, see a deck that uses KO effects and Sunburst to manage your opponent's board and also keep your own characters alive use Injustice for All pretty effectively. Johnny Quick would be key, as off init on 2 you can use him to swing on your opponent's 2 and flip up either Sunburst or Total Anarchy.

Shadow Assassins (the card in question) aren't Concealed. Their a visible 2 drop army character without range and an ability that works best off initiative. Woohoo.

I think Sunburst/TA is crucial in making Injustice For All work. Allowing for direct attacks is the biggest issue.

Yeah, I know what they do. :) I was confused by the whole "can't be hidden very well" part and thought tchalla might have been talking about different characters. I see now he meant they can't be protected and attack as they don't have range.

There is also The Joke's on You! as an option.
