I'm not much for card/deck games most of the time, but this one actually got me hooked a bit! I think the reason behind that is how well-designed the UI is: while there is a tutorial to guide you through the process, it's more that the UI has so many little touches in it to help you learn everything. For example, I love how you can hover over almost everything, even things that are not cards, to get a info pop-up. Also, I like how certain elements are animated, such as when you use a medic to support a card, you see the wrench icon get dragged over, increase the attack, and then disappear, which visually shows you how the process works. My complaints are mostly minor: for one, I missed some of the tutorial information since the text and some of the guided selections didn't pop as much as they should (maybe increase their text size or give it a background, and increase the pulsing glow of selections) and two, the gameplay could use a little bit of extra excitement, you know, little special effects and animations for attacks, maybe some cool banner transitions for phase changes, etc. For the most part, though, very solid job!
