M13: Thragtusk and new Liliana and Ajani !

Thragtusk follows the trend of creature who creates token if he leaves the battlefield. A good addition for a Thromok EDH deck.

We already had Brindle Shoat, this one cost a lot more but also give life when he comes into the battlefield.
He's also fantastic in a deck with flicker abilities, like Deadeye Navigator.
This beast is a 5 power creature, so you can also play him in a  Mayael the Anima deck.

The new Liliana is a planeswalker that you should play in a mono black EDH deck (Griselbrand, Iname, Death Aspect, Korlash, Heir to Blackblade) that wants a lot of black mana, along cards who can generate lot of black mana like Cabal Coffers or Altar of Shadows and finish opponents with Exsanguinate.

Being able to guarantee a land drop each turn for no mana is really great !

Note that she isn't able to win a game by herself.

Ajani is a strong planeswalker. He's not able to protect by himself but he is cheap.Build an army and wait until you can use his ultimate. Again, this Ajani relates to your life number so find way to increase it.
