Having seen the full video, some observations:
- Tom doesn't know the cards. (see Zombies and Ghost) Which is fine, I guess -already knowing all cards in a kingdom might seem like obvious but it's not to the real casual players. Those players might be better served by playing more of the Dominion they own, so hey that's fine.
- He seems to really hate Fool - I've never played it IRL but I can see it being fiddly. Still, if you have ever King's Courted a King's Court, Fool doesn't seem worse (by design).
- I just don't see a lot of the criticism he moves against Night cards. Back in the day, Durations were more fiddly, Treasures-that-do-stuff more confusing, Reactions-to-weird-stuff more outlandish, and Crown more enraging. It feels like that horse has already bolted 8 expansions ago...
- Regarding Hexes and Boons, I don't mind them. But again, I see the fiddliness argument, but it doesn't seem too bad. I really have trouble believing statuses are as bad as he paints them.
Ultimately, I think that Tom is not the target audience - the target audience being people who know the Dominion sets they play with and want to try something different.
The fact that he had already reduced his collection seems to support this hypothesis.
