Forge is one of my favorite cards to play in Dominion. When you have a Forge in your hand, you look at your cards differently: in addition to counting actions, buys, and draw power, you now also need to add up card costs. Rather than playing a Rabble, maybe you could forge that Rabble with a Quarry (and a couple Coppers while you're at it) to get a Platinum, et cetera. Unfortunately, Forge has one of the lowest win rates among the Prosperity cards. So, I thought I'd share a neat little Prosperity-only combo that shows off some of Forge's power.
In order for Forge to be anything more than an expensive Chapel, you need to have cards whose total costs add to something useful. In a Prosperity game, there will probably be Colonies on the board, and so you need cards whose costs add up to $11. Unfortunately, this is not always the easiest thing to accomplish, and you will usually be stuck with forging whichever unrelated cards you happen to draw with the Forge. It would be great if there were 2 types of cards in our deck whose costs added to $11 that we could just keep forging into Colonies.
Enter Hoard. Hoard's most obvious purpose is to keep your big-money deck running into the late game, by counteracting that victory card you just bought with some coin. But, this is not Hoard's only strength. If you can muster $5 with a Hoard, if you buy a Duchy, you gain a Gold. Guess what: $5 + $6 = $11, exactly the combination that Forge needs! So by buying a hoarded Duchy, you automatically get the fuel you need for your Forge.
My Council Room search didn't yield any games that demonstrate this combo, but I played this combo in a face-to-face game yesterday and prevailed. Forge is a difficult card to simulate, but based on what I got out of the simulator, this combo seems to work best when there is a helper card to get Forges early in the game (no later than the third reshuffle), especially if it costs $5: Vault and Rabble are two examples.
It's not clear that mixing Hoard and Forge is enough to beat a fast King's Court / Grand Market deck, but, in my opinion, it is a whole lot more fun to play.
