needs to be refined
first and foremost, there is a gross lack of attack cards making a battle takes forever. second, most of the card r useless in most situations. to take that one step further, sometimes any card in my hand would actually benefit the opponent (hehe, this was especially true when the comp cut off "3 of my arms" thus reducing my hand to 3... i never drew stitching that match either). third, trying to play cards together that would benefit each other is almost impossible because of the sheer number of card types and how slowly new cards r drawn. for example.. i was dealt 2 "dishonorable blow" cards the first round, i saved them thru the entire match (which lasted more than an hour) and i never drew a single card to make the opponent bleed, which would have resulted in a bleeding level of 4 minimum. i understand that the player is not supposed to get the cards thay want all the time... but having the card drawn be random is a little silly... the deck should be cleared out before it is reshuffled (unless perhaps both people draw from the same deck???). fourth, im not sure what hazumi does besided when combined with a card directly. as in 10...20...30..? i think my attack and defense each raised by 1 for every 10 points of hazumi, but if that is all hazumi does then its really not worth it considering attack and defense will be changed by regular card much more often and in greater degree. not to mention the cards that hurt u more the higher your hazumi is. fifth and lastly, i felt your desription in authors comments was a bit inaccurate. for me this game playes much slower and less lethal then Magic.
all in all u have build yourself the framework for a very nice game. with minor adjustments u could make the game much faster and have a much srtonger sense of urgency.
