Im played the dreadful deck. It got me to legend,
…and again, MC isnt the one carrying the whole deck. Its the deck carrying MC.
If the MC were changed to another good 6 drop, the deck still gonna ruled the meta.
About the paladin secret power level. Actually ALL secret are bad. The ones made them playable are the support. Secret decks, either paladin, hunter, or mage, exist because the secret support. Erase those support, and none of the decks would have existed.
IMO, paladin secret is the most powerful from other class. The cheapest compared to its value and most consistent.
