Rogue discover card is actually pretty great. It's like farsight but better imo. Cheaper and slightly more controlled with the drawback being that you can obviously low roll your picks. That being said there's a great chance for it to highroll being able to pick from 3. Also, ANY chance for another Flik is insane. This will be slept on.
The responses so far to the shaman weapon being bad are baffling. The card is just straight up insane. As someone stated the minion comes after the spell so scheme or earthquake trigger before hand. For bonus points, you can re-equip it with that new 4/2 pirate. This weapon is in fact so insane that I feel it alone makes control shaman viable. Also, VERY good synergy with their new 10 mana spell that was written off earlier. Lots of good 10 drops legendaries including colossus of the moon which would pretty much be an instant win.
The demon will be the new corridor. Any class that plays 2 power on turn 1 can make use for this. 1 mana after a lifedrinker. 2 mana after hunter hero power. It's just a house and is likely gonna be nerfed to 5. Not to mention early weapons. It's just insane.
Warlock spell is broken in handlock. Just more aoe to discover or whatever you might need. Can play it and twisting on 10. Great card.
Hunter mech may revive the archetype. It's also insane especially with how many mechs are just 1/1 flooders.
Warrior already had the best 1 drops and this is no exception. The class just has insane 1 drops and this ensures it will never have a bad early game again, as if it already didn't.
Water elemental is too slow and low stated, won't see play.
The battlecry minion is a tech card whereas loathed was standalone good because disrupting spells is infinitely more applicable than disrupting battlecry. Loathed protected your board from aoe which is what made it so strong. If battlecry heavy decks (lackeys) become huge this will see play as the stats at fair. I think it will solely depend on lackeys.
These are my opinions but of all of this mark my words this shaman weapon makes control shaman viable by itself, and combined with the pirate it's just bonkers beyond bonkers. It is both tempo and value in 1 card. I am actually flabbergasted that people say it's just "meh."
