Forum:Blackwing wing kalut vs macro cosmos

darknage5k/ blackwing kalut vs macro cosmos MY friend and I were dueling and he activates macro cosmos and then attacks me with his monster which has higher attack than my blackwing monster. Then I use the effect of blackwing kalut, but he then state i cant because of macro cosmos. I oppose against hes statement but I then just let it slide through. Does macro cosmos stop kalut effects?
