Forum:Evolzar dolka eff

Player A has one Evolzar Dolkka in face up attack position and a face down spell/trap card and player B summons an Ancient Gear Gadjiltron Dragon and is player B turn. Player B attacks dolkka with Gadjiltron, however player A uses dolkka's eff on Gadjiltron, preventing player A to activate traps/spells when Gadjildron attacks, and destroying Gadjiltron. Is that even possible for player A to use Dolkka eff like that?
