Even if you don't get the best shuffle luck to begin with, you don't really make things better. I count 6-7 terminals by T10 with one worker's village. I know the salvager was intended to trash the estates, but your deck can't do a million things at once with only one village. Get more villages, its a limited resource. Now say there was also vanilla village in the game, then maybe you can delay it, but the difference between 6-4 or even 7-3 village is great in a deck where all you want to do is play multiple actions.
I also think your deck would have cycled better if you focused getting wishing wells instead of silvers. Instead of buying a lot of one-a-time trashers to trim your deck, often buying cards that cycle (wishing well) speeds up the process better. The deck's goal isn't to buy really expensive things like provinces/colonies, its purpose is to pester with constant goons and also play multiple goons. Silver does not help you here and actually makes things worse. Wishing well doesn't help you that much in increasing hand size/cycling, but it doesn't HURT. Of course if you do do this, then you would need to manage your dollars better and ensure you still get to $6 relatively early but to follow Dondon's point, a T9-10 Goon isn't horrible if you've set your deck to play these cards more often.
