Basic fullbring is limited telekinesis of the object in question and maybe acceleration. This we know. What Tsukishima did this chapter was basic time travel when it was established his ability exceeded no more then mental insertion of his presence in someone's history. Now if it works on artificial things i can see him becoming familiar with the object in question. But the trap thing was too far. A simple sword fight would have been cool, but no matter what ability he has in the end he is no threat to Byakuya.
