good job on the changes, it will take some work to find the real broken cards now.
I'd also like to point out that only global enchantments ever came into play undimmed so Foul Termite Swarm and the like haven't been changed. The only cards this actually changed in Arid Encroachment which I do think was off since it didn't act like other enchantments.

Building changes:
Bamboo Watch Tower: 2 flux -> 3 flux
Beacon of Calendor: S -> SS
Emerald Spring: 3 flux-> 4flux, -1 health
Dank Pit: 2 flux -> 3 flux
Exhausted Mine: M -> MX + ability changed
Magnetite Beacon: 2 flux -> 3 flux
Ord Stone: no change
Walled Outpost: 3 flux -> 4 flux
Mogi Nest: 3 flux -> 4 flux
Vapor Mahal: 4 flux -> 5 flux
Foul Obelisk: D->DX

I think thats a fairly complete list of the building changes, if i missed anything or made a mistake let me know

Thinking again about ascent nerf, another card come to my mind....Negate

Ascent: 4flux 1 Domain

Negate: 1Flux 1 Domain

Ascent: U lose the flux, u have your card back
Negate: U lose your card, u have your flux back

Ascent only hits creatures
Negate hit entities, but only if its comes into play this turn

IMHO, Negate was better than ascent, and now negate is a loooooooooooooooooot better than ascent.

Following this balancing pattern, negate isnt a card to think about?

Negate can only target things that come into play on rounds though, so if you can't see it then it is stuck in your hand.

I quoted FiestaVaca at the top because I believe it represents a fundamental flaw in the understanding of online card games. Many people may hate me for this, but I'll go ahead and say it: there's no such thing as a balanced card game of this nature. There will always be certain combinations of cards which work better than others in the cost-benefit analysis. As has been my belief from the beginning, it is impossible to alter a single card in this game without changing two dozen more in perhaps a fool's errand attempt at balancing. That will only increase with the number of expansions released, the assumed addition of two new domains at some point in the future, and the exponential increase in exploitable combos.

...

ALL OF THAT BEING SAID AS AN INTRODUCTION, I support these changes not because they balance the game, but because they force the strategy into a direction that the devs I believe had in mind - and one which I believe should be the central focus of the game. Buildings take a little bit longer to get out, so you need to play a little bit more "defense" if that ever existed in TFW before. Sylvan rush becomes slightly more difficult, and the all-too-permanent effects of enchantments can in some way be countered, even if only for a turn. Does the change for Benefits of Spectacle kill the card? Not at all, but it certainly is no longer an alternative winning strategy. You still gotta conquer flux wells, you still gotta build buildings. And that, at the end of the day, is what TFW was supposed to be about in my mind.

The developers have the power and right to make changes to cards - particularly this early in the game's life - which direct the strategy in the way they had envisioned. For that reason, and that reason alone, I think these changes make sense.

Well, people are still mad about the changes.

Now MF is the strongest. But thats fine. Its normal for a certain domain to be stronger. Thats just life.

However. To prevent people from getting angry with the new set.. you should give everyone 3 phantom cards of every card in the new set so they can beta test them. It will also ease in the new change of the economy with the cards. In fact I dont see any other good way to go about it unless you plan to do a mid set rebalnce again.. which turned out poorly. Not neccesarily in the way they were balanced, but the way the people were overall pleased with a balance at all. I beleive cards are automatically balanced in the way that everyone can use them.

Also.

Do not compare ascent to negate. Ascent is fine as is.. Now charm may not drop so much in price. Id avoid continually balancing the game. Its much better to spend your energy releasing new sets. Maybe MF will have a certain weakness with the new ones? Ill avoid leaving any false hopes here on what because I dont know. But i could request more 1 or 2 life high attack creatures?

I was a bit sad to see the list of these "balancing" changes. About ascent, it's true that it was partly to blame for high flux-cost creatures being fairly useless. But a cost of 4?? Honestly, who will use it now? And then the mahal, flux-cost of 5 makes it almost useless, since casting it again and again is way too costly now for most decks. I don't even think it was overpowered to begin with. In the long run, you lose a lot of flux and draws trying to keep mahals in play.
