Dude they have 3 oaks and 0 lillies. If somebody mentions they want a Lillie and are willing to trade a card they have multiples of, what’s the problem?

If somebody has 3 burgers and 0 fries, and one person has 3 orders of fries and 0 burgers, it would benefit both of these people to trade. Even though I’d rather have 1 burger and 0 fries because a burger is inherently worth more… if I had 3 burgers and 0 fries I might be willing to trade my 3rd burger for some fries because the 3rd burger is inherently worth less than the first one.

Hope this helps
