Fortress Lord Wriothesley

Whenever Fortress Lord Wriothesley deals combat
damage to a creature you may exile it under
Fortress Lord Wriothesley. That creature remains
exiled as long as Fortress Lord Wriothesley is on
the battlefield.
Fortress Lord Wriothesley gains First Strike if three
or more opponent's permanents are exiled. If six or
more opponent's permanents are exiled then you
may draw a card at the beginning of each of your
end steps.
