I have Ladd+Dragosac+Token on the field, EEV and chalice face down. my opponent tries to summon High Priestess of Prophecy. I chain EEV. Since its chain link 2 Ladd cannot negate and I get EEV effect right? Further more, I was also fairly sure that tribute Ladd is the cost. Subsequently my opponent cannot summon Priestess. Am I correct in my deduction?
