Dark Queen

I'm on my second Miitopia playthrough, and I just beat the Dark King and Queen with 3 level 44 Miis, one of which had just joined my team from the Traveller's Hub! There were 2 Elves (me and the recruit), and one chef. I guess 4 turns of horseplay/whispering did help out a lot though. I find it strange, as I found them quite hard on my first playthrough.
