Dominion Strategy 
Secret Chamber has the same effect as Vault yet it costs 3$ less and even has a reaction effect. Why the hell would someone buy a Vault, other than to trash it as soon as possible?
+2 cards is a big difference. It’s a guaranteed Gold or Grand Market with Vault.
Have you ever tried the game a bit on isotropic? You can play many games there in a short period.
Please think a bit more before spamming with your posts. Otherwise there is an impression you want to insult the designer or simply troll.
Can you play multiple Quarries at the same time for even lower prices?
Yes.
Thus 2 Quarries equal 2 cheaper Golds when it comes to buying Actions, and 3 are overkill. One can trash his Coppers and stick to buying Actions that later on autobuy Victories while still defend or attack others with Attacks/Reactions. Sounds simple and effective.
quarry reduces prices for action cards only, not gold.
The Counting House card could easily be called Shoplifter with that sort of effect. XD
4 card Strategy: Buy two Monuments and then a Village and a Steward. Repeat again and then start trashing Coppers and Estates. Keep the ratio of Monuments/Villages at 2:1. If you get lucky with 6 coins from Village chaining, go for Goons. If you get even more coins, just for security buy Provinces or Colonies. After that you just farm VP tokes with no real need of any other type of card. You may be getting from 1 to 4 VP each turn and no enemy attack can possibly hinder you. How does it sound?
you really only want to have one more monument than village and if you choose to get more than 3 monuments you risk having a hand that will only get you 1 vp so you want more villages in such a scenario. btw the reason 2:1 is off is because 10 monuments won’t be played by 5 villages and its better if you draw your villages first then play monuments since drawing monuments first might not give you enough actions. on another note, goons is much more powerful than monument and if thats in play you can probably improve your strat by ignoring monuments and trying to get multiple goons in play. Also, militia could slow down your vps and witch could too. The biggest worry is that with steward your opponent will probably be able to get 8 colonies fairly quickly and will probably get the 80 points from them and end the game before you can get 80 points from your deck which won’t start generating 2-4 points until later on in the game after significant trashing. I think buying only money and a steward would probably outrace your idea but I’m not sure
A goons engine is almost certainly the strongest thing on this board – it is on the big majority of boards where it’s possible. Cursing attacks take precedence, but money-based stuff is just going to stall out. Buy your steward, get a little money so you can hit 6, and then grab as many villages and goons as you can as quick as you can. The attack will really slow down the money player, as will their greening, and you can really rake in lots of points with the goons.
what is the definition of in play?
There’s a “play area” where you ordinarily put cards when you play them. If a card is here (as opposed to being in your hand, your deck, the trash, “set aside” by a card like Haven, or somewhere else) it is in play, and vice versa.
Note that the question of whether a card is in play is distinct from whether it has been played that turn. Sometimes cards are played and wind up somewhere other than the play area. (It’s theoretically also possible that a card finds its way into play but you didn’t ever play it; but there’s currently no way for this to happen and probably never will be.) Feast is briefly in play but promptly moves to the trash. If you play the same Goons twice with a card like Throne Room, there is still only one Goons card in play.
You can even use this rule to play little tricks. Play a bunch of Coppers, trash them all with Mint, and then buy a Grand Market which you couldn’t have bought if you still had Copper in play.
Easy: 1 King’s Court, 1 Throne Room, 1 Monument, 1 Bishop, and 1 Platinum (or Province if you want the game to end fast). Use the Throne Room on King’s Court, use the King’s Court on Monument and Bishop, trash the Platinum/Province with Bishop and repeat. 10 points per turn guaranteed.

I think that’s the best possible 5 card hand, but let me know if you found a better one.
