Xenoid, Lord of Xenophobia

Lifelink, indestructible
When Xenoid, Lord of Xenophobia enters the
battlefield, exile all creatures your opponents
control that do not share a creature type with it
until Xenoid leaves the battlefield.
Whenever a creature enters the battlefield under
your control, you may exile target creature card
exiled with Xenoid permanently. (It will not return
to the battlefield when Xenoid leaves.)
