Alzegad's Adaptive Exchange

You touch any magic item which you have been attuned with before and can instantly become attuned to that item for the duration of the spell.  If you are currently attuned to the maximum number of items you choose one of those items to instantly lose and be replaced by the item used in the casting of the spell. Once the spell ends you lose attunement with the new item and any previous item it replaced remains unattuned. You may reattune to either through the normal means of a short rest or subsequent castings of this spell.

The spell automatically fails if the magic item you choose to become unattuned from is cursed.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the duration of the spell increases to 10 minutes. When you use a spell slot of 9th level or higher, the duration of the spell increases to 1 hour.
