It would be a bard subclass but I don't really know 5e to well. My 4e Halfling bard had virtue of cunning, so I could move a ally 1 square (range would be 5 + int. mod. squares away) when a enemy missed as a free action. This was the key feature I liked about the class, a good amount of spells I had let me play chess.
If anyone has a recommendation what subclass would fit that, id vote for that one.
