I have other suggestions I will compile, however…
One I would like to see in the very near future is the ability to designate a defense deck.
If I want to use the same colour for both attack and defense, I have to switch cards around all the time, and this game is already a huge time sink.
Give us the option, PLEASE!

I highly suspect that you’re referring to the Magic the Gathering Puzzle Quest. While your idea isn’t a bad one, this isn’t the right forum.

One thing can be taken from this, whether you’re playing MtGPQ or MPQ, it’s still a time sink!
