How about: If the "AoT/BoT" was shot from the Archer, it would warp back in time in short use "Reverse Time" on itself, therefore creating a very powerful CC that still matches it's theme (objects travelling faster than light move backwards in time) but yet, is still very balanced because there will be a 1 turn delay of using that arrow again, and you take a huge risk in clogging your deck up to repeated draws of one card.
