The fake copies do nothing (can't attack, deal no damage and do not have any effect) but confuse your opponent/ make your opponent test for the real minion. They are revealed when they take damage, are being targeted by cards/hero power or when the real minion attacks or takes damage.
"Some are keen to bring pain and despair to the world. Ner'Zhul has done that by accident."
Card based on Kil'Jaeden's plan to take revenge on the Draeneis from Draenor, because Ner'Zhul takes part on it thinking he's doing a good thing. That's why it has sinergy with schemes even if it's a Twispell.
An attempt at making a fair AoE for Priests. This is great against Aggro decks...provided they attack first, but only situationally good against Control and Combo who know needs to consider if they should mindlessly hit face or not. Think of it as a super
effect allows you ensure another attempt against a rather swarmy Aggro deck (*cough*
Soul of the Forest
*cough*), BUT now your opponent is aware of its existence, allowing for counterplay (e.g. they could just not attack and build up a board AND THEN attack, either way you still get to stall a little).
