Helm of Mischief

At the beginning of your upkeep, create a token
that's a copy of equipped creature except the
token isn't legendary if equipped creature is
legendary. It gains decayed. (A creature with
decayed can't block. When it attacks, sacrifice it at
end of combat.)
Equipped creature has shroud. ( It can't be the
target of spells of effects. )
