>which is better a balanced deck or one focused in just one atribute?somewhat balanced but more speed than others. probably 3 speed and then either 2stam/1wit or 1stam/2wit or 1pow/1stam/1wit etc. also depends on the character, Bakushin and Urara want all speed for example if your only concern is beating the career, maybe 1 stam if you want to do team trials with them
