I'll be honest - Cursed Blade, at least in this challenge, should be kept.Because, since all the minions of your deck are taunts, you won't get hit unless you run out of minions. Therefore, if you can save your weaker minions until you use Bolster to bulk them up, you'll have a better time. And i guarantee you'll never be hit again apart from those three hits (or maybe two, since by the third charge you'll most likely have the board in your favor).Also, i believe that Pit Lord shouldn't be discarded if you have two early minion drops. By your third or fourth turn you'll most likely control the Rod of the Sun, and the opponent's counters to recover the Rod will happen starting from the fifth turn. Though you should mulligan him rather than expecting a second early minion to show up on your hand.
Is there any particular reasoning behind the ordering in which these cards are displayed? Because if there is, I can't figure it out. It's not by name, not by cost, not by quality, not by type, not by how good they are,...
