I play Wild because I have many cards from over the years but am having trouble using corrupt cards.
The XP award for using Corrupt cards is just sitting there because I don’t have decks that contain then.
What’s a good deck heavy with corrupt cards?
That quest is broken atm, you have to play the corrupt cards without corrupting them, so just roll past it.
I think in this case, it is not about the quest, but rather the achievement.
Yojimbo, I’ve created a warlock deck. Cascading Disaster is pretty good corrupt card. I’ve put other corrupt cards there too including Y’Shaarj, but the deck is quite weak 
The numbers say it’s not great, but I’d say clown Druid and stick in the Druid corrupt 3 drop. My guess is that it’s too slow, but as such it kicks my **** a fair bit 
Well, I have created a Druid deck with three Old Gods to do a quest and it was quite fun I even did not have to play Survival of the Fittest to win, but I guess, I just got lucky I’ve resurrected some earlier minions with N’Zoth corrupting Clowns and/or Strongmen along the way, and then used Y’Shaarj to play corrupted cards again.
