This card-based game will challenge your strategy skills against a computer. To start, choose a name for your player. Use the meter at the bottom of the screen to choose how strong your deck is. If you think you can do a better job of constructing a deck, click Use Custom Deck to build your own. Then, choose if the other player is a computer or real person. Set the deck strength again. Then, you will receive five cards at random. At each turn, you get to play a card. Click and drag it to the middle of the screen to put the card into play.
