Building a deck is quite fun, so I thoroughly enjoyed this one. I don't I ever completely understood how damage/poison works, but it didn't matter ultimately. I just threw everything with a big number on the enemy. :D
The graphics and presentation is pretty nice. I liked that there is even a story with an intro, this is very nice to have. It took me a couple of tries to defeat the golden knight, but once I had a good run and prepared the right cards everything went smoothly. The game ends rather abruptly, but apart from that it feels very polished.
It was a great experience playing this game. :)
