I found out this combo/engine for the first time today, and I'm wondering if anyone else here has tried it as well. This is my first time posting to the forums in a VERY long time, I'm trying to climb back to top 100 again.
So the premise of this engine is that you can use sacrifice early to eat all your estates and copper, and then start cannibalizing your deck to rush provinces (I was able to get 5 by turn 14 when I tried).
So, how do you actually do this without running out of things to trash-for-benefit? Stonemason. Think of stonemason as simply adding 3 cards to eat to your deck with one buy. It almost doesn't matter what they are, but having simple cantrips are probably the best, because they allow you to draw the right cards more often.
The execution is roughly as follows: open Sacrifice/Silver, get a second sacrifice, then start buying up a ton of stonemason overpay actions as soon as you're down to only 2-4 cards left from your starting deck. The only real important part is to make sure you have enough $ in your deck to hit province if you draw your whole deck. You don't need more, so prioritize getting the engine to run smoothly.
I'm unsure how well this combo will work with which cantrips, but Chariot Race seems like the best option, followed by stuff like hamlet, market square, and possibly even oasis.
