I played your game, I am a big fan of Yu-Gi-Oh and this did have some similarities to that and Magic which I think is good. It feels early development except for the Art. My thoughts on the game
The different Attributes didn't seem to play a huge part so adding something that makes this matter would be nice.
When the opponent played a card it went by too quickly to read let along see the art, sometimes a curse would be played and I would have no idea why or how it worked. A setting that allowed you to turn on and off auto skip on reading cards could solve this so that players who are experienced don't have to wait and new players can take their time.
When battling the card shake makes it hard to read the text, maybe some other effect that shows that a battle is happening also informing the player who the attacker and who the defender is during the battle would be nice.
A tutorial would be good to have, learning about Atk Time, that Draws result in no winner, other things related to general play
Minor things that I think should be addressed, Grammar errors on the cards, the End button should say Next Turn or End Turn and also should be a different color (like red) from the decks because graphicly it just blends in, when I went to view the Tomb I found it difficult to escape.
I think it would also be good to have a way to view your entire hand as apposed to clicking the eye for each card
