Forum:T.G. Wonder Magician vs Black Rose Dragon

Here is the senerio: On my field I have a T.G. Wonder Magician and Junk Warrior. My opponent uses a black wing deck summons a level four and a level three monster the proceeds to synchro summon Black Rose Dragon and call priorty to activate it's effect. I then use T.G. Wonder Magician effect (which say i can synchro summon in my opponents main phase) to synchro summon T.G. Blade Blaster. The question is can i activate T.G. Blade Blaster effect (which says i can activate its effect in my opponent turn except for the damage step) to remove itself out of the game at that point, hence missing its destruction from Black Rose Dragon effect?
