Would this be suitable for a highly precocious 4-year-old?

I would say yes most definitely. What my grandchildren enjoyed about this product is the cards to give them ideas of things that they can make with the blocks they found it very entertaining and it's been inspired in inspired creative and talking to them things if I following visual directions

Can you purchase more challenge cards?

I do not know but I would suggest that you try to email the company that makes this item you may be able to purchase on there site, Or try amazon maybe they have a generic type of card
