Phantom won't work as an opener imo. Also, imo the opener should be a song from the NOTB-SSOASS period for this tour. If it's a "best of" celebration tour, it should open with a hit imo. I'd personally prefer Moonchild, but to be honest Aces High, TNOTB and even the Trooper seem possible. The other one that could happen is Murders, because it was the opener for the Beast on the road tour, but I don't think so. BQOBD would be a good opener, but not for this tour imo. Maybe I'm biased because I don't like the 90s albums and I think they won't really play many 90s songs. If I had to choose the opener, it would be Prowler obviously, but not gonna happen (I can only hope).
