They're on to me!
Though, his description is bad. I'll say it straight up, I'm taking credit for making this deck. I've been using it for a few days already and so far I've only played against it twice in probably a 75+ games.
That said, his version of it is not great. Using a Redanian Knight is silly since its an 8 strength card with no ability. I started using Reinforced Trebuchet because after I used Adrenaline Rush and Promotion it will still do damage every other turn to the opponent. I've since switched over to Poor Infantry (3 strength, makes a copy of itself when it spawns). The benefit of Poor Infantry is two-fold, you have multiple of them out on the table so you can stagger your buffs to protect against a Scorch. And then after you buff it up, us Adrenaline Rush, then copy it with Foltest the new copy then spawns a third copy because of the card ability. So you have three hugely buffed card, all with Adrenaline Rush, and then turned gold going into the next turn. I'm currently uploading a video where I skipped round 1, then on round 2 buffed up to 503 strength, then carried 414 strength over to round 3.
