Why not have AST deck customization like Triple Triad?

We could even go as far to add more cards would love to see some debuff cards

There is a thread here:

Suggesting that you could play cards on an enemy for a debuff instead of a buff. I would also support that idea or even some debuff cards on their own that you had to make decisions between. In combination with a deck customization system, it would allow for some real decision making for what you bring into different content.
