and people who say that this game is luck obviously don't know how to form an impression of their opponent through his actions and guess what he/she is liable to do in the latter half of the game.
no, PeterVincent, Tafari is useless as his powerful attack can easily be avoided with a range switch and his nataural ability actually makes him useless strategically as you cannot trick people into thninking you're using it and intercept. Although honestly i'm more of a longe ranger, he may be usefull against onimaru and some other crap cards.
One bit that's ben overlooked is the level of you oponent. I suggest that defeating an oponent of a higher level should increase your chance of getting a new card. I really think it would be a nice addition to the game.
