Forum:Nine Branches of the Yang Zing

My Hot Red Dragon Archfiend Abyss attacks the only face-up YZ monster my opponent controls, inflicts battle damage and activates its effect. Can my opponent activate Nine Branches of the Yang Zing at that moment? Is his YZ considered as on the field at that time? Mofiz (talk • contribs) 23:15, December 21, 2016 (UTC)
