Arena Defense Team

well, you can do that if you don't mind getting a somewhat low score

Since I'm particulary salty after 50 duel crests spent I will say what are the worst defense team you can put.
-Counter to the Askr trio of the week
-Everything that warps, so guidance, WoM, etc.
-A dancer with both things

A dancer alone isn't bad, it's a little predictable, but many things together it's what destroy other teams. So if your dancer has some warp skills and those 3 magicians have high speed/high attack sure. Trust me.
Also if the others magicians have some good merges then you can get even the max score, not much is needed to get it.

Generally speaking, use a dancer on your defense team. Everything becomes harder to deal with. We don't need a huge score for max feathers.
