its a worse Doomsayer for half the mana. Better than Doomsayer against small things and worse against big things. We've got a lot of big stuff and a lot of healing in the the game now so most of the time you probably won't run this over Doomsayer since the text on Doomsayer is just so much more powerful.
nah, everyone compares it with doomsayer, but this card is 1 mana less. Against mid-range deck with large minions, this may be weaker, but against most aggro, this is more annoying to deal with, because this only costs 1 mana. Not to mention if you buff hp for it (and heal it back again), it can still trigger against. Priest can utilize this to have few turns in advance with aggro decks.
Freeze Mage could find a spot for it and run along with Doomsayer to increase consistency of freeze clears. Most decks have an answer for a single Doomsayer, some have answers for two of them. But none has four.
I think the card is incredible. Against an empty board, your opponent literally can't play any minions that have 5 or less health. If they play a bigger minion, it's gonna chunk 5 health off immediately on your turn. If they remove it, they just spent removal on a 1 mana card. You can play it Turn 1 against any deck that requires a fast start to dramatically slow their game. You can buff it's health to make it a multi-turn threat. This card is just fantastic.
I voted Very Good and I'm looking forward to utilizing it in what I imagine will be several decks in the future.
