It's okay. There hasn't been any positive feedback to Meadow, so i guess a clear "It's no good" statement helps me make a cut and let it go. So i'll let it go.
About Sultan, i like to compare it to Oasis: It's worse for Estates, Shelters, Curses and unwanted actions, but better if you have no junk (not even Copper) or with Duchy, Province and alt-VP. Unlike Oasis it only pseudo-sifts, and as it fills your deck with cards it reduces the chance to collide itself with VPs which makes up for the fact it gives a staying advantage. Explorer is terribly weak, even compared to Squire. Unlike Sultan, it at least doesn't need a Duchy normally to gain Silvers.
I'm really grateful and flattered you tested my cards. Really,thank you
The fact that Sultan doesn't work awesomely with Great Hall is a bit of an unpleasant surprise, but then again discarding GH negates its main bonus over Estate, being a cantrip. Even though i designed with Harem in mind, i guess "useless" Vp are a better target. Well, Harem gaining at least INCREASES your chance of a collision, so that's that. Anyhow, i guess it being okay is something i can live with. Not every $3 can be Scheme. You can always pick up an early Duchy, though i guess you'd need good sifting to get more out of it than that costs.
About Politician, you raise a very interesting point. Making it one choice might or might not make the card less political. Actually, i can imagine a case where Alice says "Why do you let us gain Silvers? Bob's playing Big Money and you're just helping him! My Torturer chains are the only way to stop his Treasure madness!" (added drama). Long story short, i guess it doesn't harm the intend of the card as much as it improves it.
Edit: I just realized a choice for all makes Politician rather similar to Governor on paper. Though the biggest difference is that for Governor you pick the choice you want, while for Politician you choose what your opponents get the least of... Still, 2 of 3 bonuses are the same. That's rather unsatisfying. Considering i still think that one choice for all might be better, i wonder whether doing Politician is worth it at all
A shame, i was pretty fond of this one...
Edit2: Seems i missed out Nobles also was on the Sultan board... Now that worries me a bit.
