The Basics - Solitaire: PART II (Magic: The Gathering)

I'm now on my third round of this new solitaire game I've created for Magic: The Gathering, and I've found some kinks to be worked out that I wanted to share with everyone. I would also appreciate any feedback you might have on this, and encourage some comments to be made below the video!

Awesome idea for when you have the urge but no one to play with. Thanks!!

What about the mechanism or algorithm that decides when your opponent's creatures attack and when they don't?
I don't want to attack myself xD
or do they just attack only when it pays them off?
