@The Nyx Avatar Is this Book of Support Card Balanced?

Of course not. It's as if you're actively trying to make overpowered and broken cards. It doesn't show you growing as a card maker. It shows you pushing to see what you can get away with. And if that's the case...stop it. You make ZERO attempts to improve a card's balance. YET you want anyone and everyone to give their two cents on your cards. Less and less people will come and review yout cards. What is there to say. Next to nothing if you don't heed their words.
