I don’t think warlock cards are designed to be fun for both parties involved in a match. These are cards designed to be mean, and to frustrate, thereby filling the warlock with satisfaction at the cost of their opponent having any. This expansion we were given curses, which are generally hated except for by warlocks, and now this. It’s reminiscent of Tickatus.
So, warlock players have two options: play a boring murloc deck, or play a semi-interesting curse deck with more decision making and which causes more frustration for the opponent than Murloc Warlock ever could. We’re sort of pigeonholed here into toxic play patterns. This is officially the griefing class.
