Big Undatakah Paladin feat. ULTRASAUR!

Da Undatakah gain the deathrattles of Meat Wagon x2 and Immortal Prelate, so you have a infinite Da Undatakah and, when it die, summon 2 minions from your deck who have less than 8 attack, and, maybe for the memes, Ultrasaur is a really good option xD

Prismatic Lens was so good in this deck, always give you a >/= 7 minion changing it cost with a </= 4 mana spell

Meat Wagon can be buffed with Sound the Bells! (x4, so it is necessary that it was before in field) or Blessing of Kings to have 5 attack and recruit Ysera or Sleepy Dragon

Who need 3, 5, 6 and 7 mana cost cards? You not if you have the Ultrasaur god
