2 mana draw a card is almost playable (Shiv). Here with even 50% chance of drawing another card (doable in a DR deck), it's quite good.
Remember the math people: with 50% of DR minions in your deck, you'll draw on average 2 cards (50% chance of drawing exactly one card, 25% chance of drawing exactly 2 cards, 12.5% chance of drawing 3 cards, ...)
Idk, the Jade/NZoth Rogues Ive seen dont play many cards with deathrattle on their own and instead play a lot of things like Journey Below and Shadowcaster. That being said, Cult Master/Auctioneer are kind of bad draw enginss for the deck so maybe we will see some strong deathrattes to make this worth it
How do these kind of spells work with spell synergistic cards like Auctioneer, Arcane Giant or Yogg Saron. Are the spells actually cast multiple times by the player or does it only procc those cards once no matter what?
