Speculation on Hour of Devastation cards

[CardAgain Sweater]

I did not see this as a thread in this forum yet; mods: please merge or delete if a duplicate thread.

Amonkhet was my first prerelease and experience sharing new cards with experienced players at the same time; started just after Aether Revolt release, and I caught up on the Kaledesh block stories. Learning about the minor characters and why they were cards was a fun suprise and added value (kudos to Wizards business planners!).

Based on the story so far and clues from Amonkhet cards, what new cards are you expecting to see in Hour of Devastation? Yes, yes; I've learned enough backstory to assume a Bolas planeswalker (foreshadowed with a brick to the face in story and in cards - Dark Intimations) - I was thinking smaller:

Djeru the Resolute - human warrior
1WW 2/3
Vigilance
Other white creatures you control have +1/+1
1W; sacrifice white creature you control, prevent all damage to Djeru this turn

We got Djeru's Resolve, we need a creature card. The abilities fit the character arc so far, right?

Nekht Despolied - Zombie Aven
1BU 2/2
Flying
When Nekht Despoiled enters the battlefield, you may discard; if you do, lose 2 life and draw a card.

Nekht back from the wastes! He was inquisitive, so draw makes sense, and discard fits mechanics. Gotta pay to play black, though.

I think both these fit themes and are not outrageous in terms of power...but I'm new. What do you think? Are there cards you are anticipating, or would like to see? What would they look like? Why do they fit the story? Maybe I over/undercosted my quick mock cards, what do you think about them?
