Senkai, the Alchemical

At the beginning of your upkeep, investigate,
then you may have target noncreature artifact
you control become a copy of another target
noncreature artifact. If you do, sacrifice it at the
beginning of the next end step.
{2}{u/r}: Destroy target artifact. Its controller
searches his or her library for an artifact card
with the same converted mana cost and puts it
onto the battlefield, then shuffles their
library.
