Kai'en, the Reconstructor

Whenever an Equipment becomes attached to
Kai'en, you may pay {x}. If you do, for up to X
target creatures you control, create a token that's
a copy of that Equipment attached to that
creature. Exile the tokens at the beginning of the
next end step.
{2}{w}, {t}: Destroy target nontoken artifact. Its
controller creates a Treasure token and a Clue
token.
