Here's an automatically-generated list of every vanilla Dominion analogy (so ONLY vanilla cards are included). Treasure cards are treated as non-terminals, because analogies involving basic treasure can be fun. Every analogy will appear twice in this list (because a : b :: c : d is the same as a : c :: b : d), so it's up to you which version you prefer.
