Jack and Queen are also fast food mascots (Jack in the Box, Dairy Queen)

Good grid

Agree with L, the cards and mascots can trade Jack Queen and King, so there are multiple solutions

Made Bob Dole angry in the good kind of way. Bob Dole approves.

good red herrings! I would say 'queen' works for sure because Dairy Queen never actually has had a queen for a mascot. The 'jack' is maybe because the Jack in the Box mascot is a clown named Jack? 🤷 Either way, great grid thanks for sharing!
