There seems to be another pin possible involving Outpost and Throne Room: Fishing Village, Outpost, Minion, Throne Room, Masquerade.
How?
A. Normal Turn: Play Fishing Village. Play Outpost. Play Minion (for the attack). Then Throne the Masquerade, passing nothing and trashing all that you receive.
B. Outpost Turn: Start with Outpost and Fishing Village in play as durations. Play Minion (for the money). Then Throne the Masquerade, passing nothing and trashing all that you receive.
C. Rinse and repeat.
Better yet, here's a way to achieve this deck by the end of turn 6, using only the cards involved in the pin. The trick: use TR/Masq to trash your starting deck, and use Minion to cycle it so that you can play that combo every turn. No KC madness!
Opening: Throne Room, Masquerade.
3. Draw Throne, Masq, Estate, Estate, Copper. Throne the Masq, trashing 2 Estates and drawing 4 Coppers. Buy a Minion.
4. Draw Copper, Copper, Estate, {reshuffle} Minion, Copper. Play Minion for the attack; draw Throne, Masq, Copper, Copper. Throne the Masq, first drawing 2 Coppers and trashing one, and then, after reshuffle, drawing a Copper and an Estate and trashing the Estate. Buy a Fishing Village.
5. Draw Copper, Copper, {reshuffle} Fishing Village, Throne, Masq. Play Fishing Village. Throne the Masq, trashing 2 Coppers and drawing 4 Coppers. Buy an Outpost, which you can afford thanks to Fishing Village's +$1.
6. Draw Minion, {reshuffle} Outpost, Throne, Masq, Copper. Play Outpost. Throne the Masq, drawing 3 Coppers and trashing 2 of them.
6.5. Draw Throne, Masq, Copper. Throne the Masq, which will cycle your deck again, allowing you to trash the remaining two Coppers.
7. Violΰ!
