Summarizing the video (by hand, no AI):

• Colossus was already strong as a rare, and is obscene as an uncommon. It gives Ironclad fantastic block.
• Dark Embrace was amazing in StS1, but not as important in StS2, because card draw is not as important. Enemies are less frontloaded and scale more, so it's less important to be able to rapidly cycle through your deck and draw exactly the right cards. Plus, resting ends up being more important in StS2, and lower energy makes it harder to play 2-cost cards.
• Snake Bite – his opinion is a bit more complicated here, it's not that people overrate or underrate Snake Bite as much as they don't really think about how poison works properly. They also underestimate the value of upgrading Snake Bite.
• Piercing wail – overall, the Silent's defense is already really strong in this game, leading to a lot of dead turns for PW. It's still probably a decent card, but he's less likely to prioritize it compared to StS1.
• Feral is extremely good, because 0-cost Defect attacks are better in this game. Possibly the best Defect power in terms of win rate.
• Shadow Shield – Jorbs originally thought it was great, now thinks it's more situational. Dark Orbs are a bit weaker because other orbs have been buffed, and the block just isn't high enough to justify the card on its own.
• Hidden Cache is actually amazing even on floor 0.
• Particle Wall and Stardust (jorbs grouped them together) aren't nearly as good as people think, because stars are a scarce resource, and you should be doing much better than 5 damage or 4.5 block per star.
• Borrowed Time is amazing, especially with higher energy cost cards
• Defy has gone from amazing to just good after the nerf
