So, I figured I would do some Discussion Time segments on little used upgrade cards.
Let's start off with Ion Cannon Batteries. This little used card might just be a gem beneath the surface.

Now first off you may be questioning how useful that really is. Well first off it is 5 points so not super expensive. It allows you to remove a command token of your choice which can very helpful if they are using Wulff Yularen or holding a token that you don't want them to have.
Controlling what bonuses your opponents have is very useful.
Now if they don't have a token you can still use this crit and it gets rid of a shield before the brace and Redirect occurs! Yay for the timing of Critical Effects!
Now, most stop there and consider that it is not a good card becuase if you are attacking a side that has no shields you do nothing. Really though, that is fine. You can instead choose the standard crit effect and just deal a face up card or even use another crit effect upgrade!
Go on and discuss!
