Soul of Jacob and Esau

Until end of turn, create a creature token
that is a copy of a creature you own, except
it has power and touchness {x}. The legendary rule does not apply. Exile it at the
end of turn. If you control more than {x} untapped lands, put {x} persistence counters on it. At the end of your turn, you
may remove a persistence counter instead of exiling this creature token.
