Quick question RE: Korhil and the Tiranoc Chariot (relevant text below):
Action: When this unit attacks, reveal the top card of your deck. If the revealed card is a HE unit with a printed cost of 2 or lower, put it into your battlefield, attacking.
What happens after you reveal a card that isn't a cheap HE unit? Does the revealed card get put back on top of the deck? Discarded? Shuffled back in?
