Ermine Soldier

You may have Ermine Soldier enter the battlefield as a copy of any creature on the battlefield, except it isn't legendary, is an
artifact in addition to its other types, and has
myriad.
(Whenever it attacks, for each opponent other than defending player, you may create a token copy that's
tapped and attacking that player or a planeswalker
they control. Exile the tokens at end of combat.)
