Some of these combos aren't very strong or have been more or less proven to be nombos. Caravan/Vault is not a combo. I'm pretty sure that Counting House/Golem isn't a viable combo. I'm not sure how Amb/Pirate Ship is a worthwhile combo. Trader/Feodum is conspicuously missing. Apothecary/WW is a fairly well-known interaction.
There are a bunch of combos are interactions that are variations on a theme. Workshop/Gardens is listed, but IW/Gardens is stronger. Chancellor/Stash is listed, but Scavenger/Stash is stronger. HT/Duke is one of many minor Duke enablers like Haggler, Explorer, Duchess, Bureaucrat, etc.
Minion vs. Scheme and Militia vs. Vault are two counters that are conspicuously missing.
