There's a reason he said "decent". To my understanding, Plot Twist decks are 4th tier. Lose against any hunter and super aggressive decks unless your draw rng is godlike. That being said, this deck actually performed better than the other Plot Twist decks I've tried.
I wish this strat was better too, a lot more fun than any of the other archetypes out there at the moment. I'm sure next expansion they'll elaborate on this strat more and maybe Fel Lord Betrug won't be wasted dust to you after all.
