@Ultimateninja711 : It´s not a glitch . Remember that your enemy has some physical defense , in your case , enemy must have 2 physical defense points . So , your sword flurry only does (5-2 def.points)3*7 damage.
Well , i´ve always had an issue with death mask , and that´s why i stopped using it : the card clearly states : "When you would die , instead you die AT THE END OF NEXT TURN", but that´s not true , since sometimes you can´t land an additional attack in this revived turn if your foe hits first , so you can´t do nothing because you die if your enemy kills you during that turn , not at the end of it.
