Keepsake Loanee

Flash (You may cast this spell any time you could cast an instant.)
Dash {2}{r} (You may cast this spell for its dash cost. If you do, it gains haste, and it's returned from the battlefield to its owner's hand at the beginning of the
next end step.)
When Keepsake Loanee enters the battlefield, you may gain control of target artifact until
Keepsake Loanee leaves the battlefield.
