Remember when the Verminion Tournament is active, you can simply retreat from 15 NPC battles instantly without playing (LovM: Master Tournament on DF) to score 150 points (10 per loss). Verminion is so incredibly unpopular this will net you a decent ranking and a good chunk of MGP.

You can also win 5 to get the challenge log MGP. To win the NPC Verminion battle you need a Kidragora and Wind-Up Gentleman.
-Send 4 Kiragora to the West stone.
-Send 4 Gentlemen and rest Kidragora to the middle stone.
-Smash them both. Send your entire team to the last stone.
-Easy win (the AI will increase in difficulty after 8 wins or so)

But if you hate Verminon, just retreat in the Tournament. This combined with Fashion report is up to 150k a week.
