holy shit these cards are nuts
new meta inc
lets take a look at these dudes:
Mad Scientist: wow so it doesn't just get you a secret, it plays it right away for no mana cost?? Secrets mage and hunters ahoy
Stone skin gargoyle: meh, heal only happens at the start of your turn and it's stats suck. could be nicefor fun decks like divine spirit priest
Stalagg and Feugen: oh boy fun fun for ramp druid and any lategame deck. even though silencing either one of them ruins the combo, they have good stats and are worth it on that alone.
Sludge belcher: Anti aggro woo, although 5 mana isn't too great for really early aggro
Maexxna: add houndmaster for op
Zombie chow: omg, AMAZING for priest and terrible for aggro. early game it gives you board control right away, late game combine it with archenai for 5 damage to face
Deathlord: super duper anti aggro, but absolutely terrible vs anything else. late game control decks might try running just one for anti aggro
Echoing ooze: interesting for buff paladin, since the clone will have all the buffs that you put on the original
Spectral Knight: oh lord nic cage pls have mercy. if you turn 1 drop him with druid you pretty much won :derp:
Haunted Creeper: goddamn so many beast cards for hunters thanks blizzard
Kel'Thuzad: super fun but ultimately one of those only good if you were winning in the first place cards. combo it with cairne and silvanas for so much fun, but you need those cards already on the field in the first place so eh
Neruar Weblord: LEERO-fuck. WHO DARES SUMMO-fuck.
Unstable Ghoul: now THIS is anti aggro. mini abomination for just 2 mana yes yes pls
Wailing soul: okay now THIS is interesting. can combo with cards that have negative effects like low hp deathlord, watchers, dancing blades, and also can stop freeze mage's stupid freeze
From the looks of it for the legendaries, first wing gets you Maexxna, second gets you Loatheb, third gets Baron Rivendale, fourth and fifth get you Feugen and Stalagg, and beating everything gets you Kel'Thuzard
So if you just want Lotheb then you just have to buy the second wing :V
Also each of the first four wings has 1 rare and the final ones has two epics
