It apparently takes multiple things into account: the board, your hand, character's health, your mana cost, and lets you Discover the best card in that circumstance. In the livestream, on turn 2 with nothing on board, it gave the options Wild Growth, Animal Companion, and Brightwing.
It seems pretty good.
Imagine this giving you Radiance when you're low on health.
i watched the stream last night with Peter and Brian, this card is absolutley amazing when they played it against the druid and got a perfect card being 4 damage to all minions, really wish they didnt limit it by putting it into Reno decks only ;(
If it works the way it seems so far, wow. As far as the "AI" thing goes, I guess it's based on answering a question like "which card, if played this or next turn, would make the biggest difference on the win rate in a situation like this?" They have the data to make this work, and it pretty much guarantees to always offer good/useful cards, if not outright great ones (e.g. if N'Zoth was still Standard, pretty sure he would be offered on a T9 play very often, given enough deathrattles are in your graveyard). Think swingy cards.
Voted meta-defining, because it looks this is the new Kazakus (regardless if it matches that power level, it will shape the meta because of the sheer fun people will have tinkering with it).
No, it will give you something to play the next turn, and it would only give polymorph if your opponent has one dangerous minion and you have 4 mana left
I wonder, will it give me Polymorph if I play this when Barnes and his token are on the board? Will it treat the token as an high cost minion and thus give me Poly or will it treat it as a 1/1 and I get Shadowbolt to kill Barnes and nothing for the 1/1 because it deems a single 1/1 as irrelevant by turn 4? Or maybe it thinks "dangerous ability" and gives me Spellbreaker?
Also will it always give you lethal damage if your opponent is within range? Let's say he is at 6 health and I have 6 Mana, will I get Fireball guaranteed? If so that's pretty sick.
I think if nothing else, this card is going to be played and put into every Highlander deck for the rest of Standard. This card is far too fun to mess with even if it never pans out the way people think. This card is pure gambling and if it works as claimed, is also extremely skill testing. How can a card be both?
This will also force players to make Highlander decks that have zero support too. Why not, the card looks to be silly fun AND it gives you cards that are not in your class. There really is no downside for more casual players.
I was looking for the MUST craft Legendary of the set and this is it. This may not win you games because of the deck building issues, but this will be META defining because of the power level and fun factor.
Only classic and basic cards so my guess is at that point it just takes the board into acount and gives you something that helps you deal with that cause I don't think there is anything on the classic set that would help you on a fatigue scenario.
If I had to put my money on a specific card I would say Deathwing
