QUEST OTK PALADIN lol
How is the deck viable? Frankly, with a semi-decent hand, it can still lose to aggro. But that’s the case with every control deck in the format currently, so I’d say its on-par or slightly below some of the current control decks. Of course, if you can tempo out a curve against aggro you’re likely to have a better shot, and with wild pyromancer and equality you can get an easy board clear. To be frank, marin is kinda a meme pick, so if you take that out and replace it with consecration you’ll have a better time. As for specific matchups, I personally haven’t had any trouble against hunter, aggro druid or tempo rougues in particular, because I never expect any of those classes to be running a control variant. Because of this, I mulligan for early game and make it to turn 10 pretty often. Whether or not they have steam on turn 10 is the big issue. As for quest mage and gatling gun preist, it can be faster than them. The same scenario applies for those classes, that being neither of them have meta aggro variants right now. So, you can expect control, keep the quest, and mulligan for burgly bully and go from there. This is a luck based game, but if you can stick a burgly bully on an empty board or one you have control over, you’re in a good spot. I hope this helps!

Stonehill defender is really good lol. If you’re wondering why I use the last kaleidasoar instead of blessing of wisdom, read my comment on Ribbuster’s response. Thanks!

In regards to blessing of wisdom, the card does seem good on paper. However, the consistency of the card is the problem. While it is incredibly likely that you will get a 1 cost spell in your hand, either from hydrologist of by drawing blessing of wisdom, there still is an off chance that you wont ever draw into it and you won’t be able to pull off the otk. On the other hand, the last kaleidasoar will be in your hand 100% of the time, and can be easily mulliganed away. Minimizing the possibility of failing the otk is extremely important in this deck, which is why I go for the last kaleidasoar. If you don’t have the quest though, blessing of wisdom is the best choice.
