Some other things are lacking in the Super Quiz, specifically cards from Dark Ages and Guilds:
Edit: Sorry, i missed it declared that DA and Guilds where not included in the quiz. So consider this post a help on how the answers would have to be expanded if DA and Guilds were included:
"Card Set" - Add Dark Ages and Guilds
"Victory card worth variable victory points?" - Add Feodum
"Card which can put a curse into the opponent's deck before their first reshuffle?" - Technically, this is any curser, provided your opponent only buys Mandarins...
"Card that can add 12 or more cards into your hand at once?" - Add Madman
"Card that makes you verbally name a card?" - Add Mystic
"Card that makes your opponent verbally name a card?" - Add Advisor
"Action card that gives +$3?" - Not actually necessary, but Poor House and Death Cart might be considered cards that give +3$ (as they give more - 4$ and 5$)
"Action card with 4 different action options?" - The same way, one could argue this should include Count (which gives 6 options)
"Attack card that specifically attacks the opponent's treasure?" - While they don't trash them, one could argue that Cutpurse and Taxman should be allowed here
"Attack card that can trash an opponent's victory cards?" - Add Rogue and Knights
"Treasure card that costs $0 and is not copper?" - Add Spoils
"At most, a Copper can be worth how many $? (Allowing King's Court)" - As noted by eHalcyon, this becomes insanely high. With DA and Guilds allowed, i would kill this question. Procession allows playing all Processions, playing all Coppersmith twice, trashing all Coppersmith and all Processions but one. Playing cards like Rogue and Graverobber, one may get some of them back from the trash, then repeat. Somehow, one will run out of Processions or Graverobbers/Rogues, but of course Processing these is also possible. at the end, whatever you did with KC can be done to play all Coppersmiths again.
