Yeah, sundials are a bit of a bitch. I still think there's a place for them in the game, but they do cause problems considering how cheap they are to play (and the Hasten ability).
As a side note, I don't understand why a card game should be compared to chess. A card game, even poker, is most of the times won if you have the right cards at the right time, uncertainness if your opponent has the card to counter may come into play as well. There is no uncertainness on a chess board, all your "cards" are there from the beginning, and you can see all of the "cards" your oppenent.
This is belated, and may have been explained before, but I believe the point being made was that the poster preferred less hidden information. Chess has no hidden information compared to poker which is predicated upon it, and therefore has less uncertainty and randomness, and a greater impact of skill over luck.
Incidentally, this is why many of the best decks try to reduce their size to the minimum possible, so as to improve the odds of drawing your best cards, and to reduce the probability of bad draws. Where there is less randomness, your skill in deck design and play is more important.
