Keleseth on 2 is good, though I think this list in Wild Format performs just better.
So many times you have all those activators in hand, but no egg. Well, now that’s not a thing anymore.
Also, the extra egg allows you to have a smoother curve. You can go Candleshot or Tracking on 1, Nerubian Egg on 2, Terrorscale Stalker on 3 and the game is usually already over.
I played this deck from Rank 5 to Rank 1 and it performs incredibly well against Top Tier decks! (check the stats below vs odd Paladin, secret Mage, Big Priest, even Shaman and Cubelock)
Anyways, you should absolutely give it a try!
Hope you enjoy it! Have fun boyz!
