Rulings
Cards are exiled face up unless an effect states otherwise.
Exiled cards with study counters on them retain their study counters even if Kianne or Imbraham leave the battlefield.
The second abilities of both Kianne and Imbraham look at all cards you own in exile with study counters, even if they were exiled by a different permanent, such as another Kianne or Imbraham.
You may choose 0 as the value of X as you activate Imbraham’s last ability. If you do, you will not exile any cards from your library. However, you may still put a card previously exiled with a study counter on it into your hand.
