Very cute idea. I'm a fan, just wish it worked faster, but unforunately not.
But you can see its susceptible on turn 17 in non-WV hands (granted had opportunities to buy more, so that's not a huge worry). More importantly, hand reductions and masq really mess this up. Then Island itself is a limited resource.
It'd be cool if it could be vamped up to a idea similar to golden deck though
Like in the colony, with peddler there, you probably can speed up the process a turn or two, (platinum/gold/gold/peddler*n)
