How about a green card called Mirror, where it REVERSES the effects of your oppenents Ability Cards. So if it gives them a G-Power boost, it gives YOU the G-Power boost instead. If it Swaps G Power, it keeps them the same. If it doesn't give You the Gate bonus, it doesn't give THEm the gate bonus. You name it, it's reversed
First one should be "So if it is supposed to give them a G-Power boost, it reduces the their G-Power instead"Second one should be "If it's supposed to not give you the Gate bonus, it gives you the Gate bonus twice"
