Reversal

Starting at 2nd level, as a reaction, you can make a creature redo its action. You can do this a number of times equal to your intelligence modifier. You regain all expensed uses when you complete a long rest.

Time Jump

Starting at 6th level, you can “time jump” as an action, using it either on yourself or a willing creature. While time jumping, time doesn’t pass for your character, and they appear in the same spot they were in when they time jumped 1 minute later. If the spot you were in is occupied, appear in the nearest free space. You must complete a long rest before you can do this again.

Time Quickening

Starting at 10th level, you know the spell haste and can caste it as a bonus action. You must complete a long rest before you can do this again. 

Selective Reversal

Starting at 14th level, as a reaction, you can target up to 6 creatures (alive or dead). These creatures go back to the state they were at when they ended their previous turn. They retain their memories of what happened. You must complete a long rest before you can do this again.
