Out of all the decks that currently run Healbot, the risk with swapping it is that you might lose the heal to an RNG roll, even with favorable odds. The decks that really need the heal might keep Healbot, and decks that require more tempo could switch to this.
My first thought is Oil Rogue. Rogue usually doesn't need the heal vs control anyways and the 5/5 could be a huge boost in those matchups. And the median minion cost is about 4 mana since they only run one 2 drop in Bloodmage Thalnos so the likelihood of getting the trigger is very decent vs aggro. This is truly a card that we won't know how consistently useful it is until we play with it.
Probably will replace Healbot in any decks that run it. You're almost certainly going to get the heal against face hunter, zoolock and tempo mage if you're playing a control deck, which are the most relevant match-ups for this card. Of course the RNG when you reveal a Zombie Chow or something is going to cause some table flipping.
Awesome card - may be the best so far. In control v control, you can play this out on curve as removal bait without worrying about the battlecry hitting. Against a face deck, this is probably a 90% chance of triggering.
This is an improved healbot that isn't diluting your deck. A shame that it competes for the same slot, rather than allowing you to curve out massive lifegain
Worst case, you get a 5/5, which isn't that bad since 5/5 is a vanilla stats for 5 drops.
Best case, against aggro, you heal yourself for 7 and gets a 5/5, which is amazing.
Will this replace Antique Healbot is the real question but because this card has stats that passes the vanilla test, there's nothing wrong running both...maybe 1 copy of Antique Healbot and 2 copy of this or vice versa.
This might be what it needs to slow the meta down.
I was so hyped at first but after a while I got concerned. On the bottom line I don't believe the +2/2 stats are worth it. I mean sure, vs aggro you will be pretty much everytime the winner but vs Control it will be a huge gamble. It could cost you the game if you can't pull off the heal.
OK, this one is good. Blizzard have kept the power level in check - but this one works so well in Handlock and super-late game control/fatigue decks. Looking forward to dropping this in existing decks.
Don't think most of the others revealed today work in existing deck archetypes, though.
