i think it would be hilarious for Mammon to be on the Nightmare Pass
King of Greed yada yada yada sure...but by his logic, he already owns everything and everyone so why make his possessions pay for his card??? at a price that he'd most likely consider as dirt cheap too (what is 40-60usd to the richest King anyway he has a literal river of gold in his country)
he'd think it's cute and would probably give the Pass for free to everyone (Bimet is crying in a corner)
