Switcheroo

You choose two objects/creatures within 30 ft. of each other that you can see(you may choose yourself). They suddenly switch positions, teleported into each other's space. The two targets must be similar in size(a Small creature and Medium creature cannot be swapped etc.), and neither target can be Large or larger. Unwilling creatures may make a Wisdom saving throw against your Spell DC. On a success, they and the creature they would swap with are not teleported. 

At Higher Levels: For every spell slot above 3rd, the range targets must be within each other increases by 10 ft. and you may choose an additional pair of targets to swap. 

When casting the spell at 5th level or higher, Large targets can be affected by this spell.

When casting the spell at 7th level or higher, Huge targets can be affected by this spell.

When casting the spell at 9th level, Gargantuan targets as big as 40 ft. x 40 ft. can be affected by this spell, and targets are not required to be of similar size.
