Hmm, I think that's up to you. If you really want to scratch it's better to only do it if it's 3x 5☆ Demon units event, because if it's just 3x Demon units the 3☆-4☆ Demon units will have also have a higher appearance rate. For the chance that a 5☆ Demon event does happen, a guesstimate would be 43%~ for a 3☆ unit and a mere 27~% for a 5☆, and they might not even be of the Demon race. You might actually have a better chance scratching a good Demon unit during a regular 2x 5☆ event. Hopefully that made sense ^^;

Some event areas give a good amount of coins, but a regular run of Wonder Park should be even better. And if you don't have any Light units to level, you can still do Gold Rush Casinos and sell the eggs that drop (High Gold Eggs sell for 30000, and Kings for 300000).
