I have been browsing some stats and found a version of carpet zoo with a 70+% winrate. it runs one copy of cauldron and this seems to be the only difference.
I have not actually built my carpets or rafaam yet as have been holding off to see what happens, so I was hoping someone who is playing the deck could relay some info to me about the deck in general and why it seems cauldron is buffing the winrate of a particular rendition of the deck.
here is the deck on HS replay anyway. the sample size is low so no doubt this figure is out of whack. it is interesting though that 1 card has made such a difference.
I guess they are fishing for cold blood maybe to go face sooner for lethal? if you use the carpet to trade in minions and get spells. could be reliable. I have always liked cauldron decks since we got the card. would be nice to see it working again. It's almost thematic in warlock decks as well I guess.
