Metallic Tribute

Choose target creature you don't control. That creature becomes an artifact in addition to its
other types, then target player other than you
gains control of it. You may activate activated abilities of that creature as if you controlled it.
"Greetings, Blessed One. We come offering a gift
of splendor so as to strengthen our bond as allies.
Although she was a great nuisance for us, we hope
that Chysila proves useful for your glorious army."
~Atun, to Cyni
