Keep in mind that shinsoo does not exist outside of the tower. It's very likely that in their current state, these exes users are weaker than the high rankers within the tower. It wouldn't be until after entering the tower that they become "more powerful" and it's unlikely that a low ranked exes would be able to enter the tower from the outside in the first place. Phantiminum was probably already a monster exes user and coupled with shinsoo he became even more of a monster.
