I once played a game with half of the pin: only Masq was around, but also KC.
So my opponent took the normal route and bought 4 Provinces.
On the other hand, I distilled my deck to KC-KC-KC-KC-Masq.
By playing all the KCs first and then the Masq, I destroyed his deck.
After a bunch of turns we were in a stale mate, so we both started buying Coppers to get out of it.
A couple of turns later, I had enough for a Remake.
