Does someone know anything about a double sided servant card? Was watching a video then the guy got spooked by a double sided assassin servant silver card and then that card sparkled and turned into gold servant assassin card shuten. Never saw a double sided servant card before and I was like wtf I play it since the launch of the game, three years ago and this never happened. Is this a new summon pool feature? Like gold and rainbow rings?
