Kaylin, Champion of the Lake

Whenever an Island enters the battlefield under
your control create a 0/1 blue Reflection creature
token.
As long as Kaylin, Champion of the Lake is
equipped with a Legendary Equipment,
creatures attacking you or a planeswalker you
control get -X/-0 until end of turn, where X is
the number of Reflections you control.
