Valar is a good card, but it has itr's drawbacks, the no claim part hurting the most.
Also there are ways around it. I liked the plot because it made your opponent think of what to on the board. If a person got a ridiculously good flop, you didn't lose the game just because of that. Now if I have a very good setup and narrow escape in my hand, it's going to be that much harder for you to recover. If I have two, it's already laughable. I think that's about as talentless as having valar in your plot deck.
