Time Erasure

You bathe every creature within range in the magic of time, causing them to act out a future that doesn't exist for 1d4+1 rounds. Once you cast this spell, you act normally until those rounds end. After that point, all damage you received and dealt is negated, all of your spells and any spell effects involving you during this time are negated, all resources consumed by you during this time are returned to you, and you are returned to the position you were when you cast this spell.

Then, you take a number of turns equal to the number of rounds erased. If you cause damage to any creature during these rounds, you lose all subsequent turns and your turn immediately ends. After you take your turns, every creature affected by the spell is unaware of any occurrences during those rounds as if they had never experienced it.
