Apperantly sting have slifer I use exchange on him and I trade my card for Slifer. Its really amazing. Slifer effect can destroy any monster that opponent summoned who have less than 2000 atk. Unfortunately that the only time for now we can have it. Because like Jinzo, RA sphere mode n monster reborn. Slifer are not in card catalog. So I assume that we will not get slifer from this event. Probably slifer is new year gift from konami.
