Ilmineth, the Eyeless Vision

Reveal Ilmineth from your hand: You may exile another card from your hand. If you do, Add {c}. Activate this ability only once per turn.
Ward — Exile a card from your hand. (Whenever
this creature becomes the target of a spell or ability an opponent controls, counter it unless that player exiles a
card from their hand.)
As long as you own seven or more cards in exile,
you may play cards you own in exile.
