A long time ago, before Standard format was even a thing, Secret Paladin was a menace on the ladder after Mysterious Challenger got printed. Underrated at first, in a hindsight it turned out to be one of the most powerful cards at the time. Those times are long gone, but new Paladin synergies are getting printed and the archetype might make a big comeback.
It’s safe to say that Blizzard has tried to push Secret Paladin this time around. Printing cards like Desperate Measures, Mysterious Blade, Commander Rhyssa, as well as a Neutral Sunreaver Spy, they really wanted to make it viable. It turned out to be a bit worse than suspected, but it’s by no means an unplayable deck – it might require some more optimization, but I believe that it will be a part of the upcoming meta.
