Yo that's crazy. I was testing my R-ACEist deck and I had Baronne on the board, CPU had Malefic World on the board. Turn 3, CPU activates Malefic World and essentially gives up his normal draw to get a Malefic draw. My Baronne negates, but Malefic World already negated his regular draw, and because it was negated and destroyed, it can no longer allow the CPU to find a Malefic. So it simply skipped its draw
