I pulled a +Spd, -Res Leila on the Mythic Banner this morning and decided to finally build a Matthew as her support partner (I will upgrade him when I get extra feathers to spare). I was searching for a second team for Astra season since my current one is running into problems. I currently have a +6 Naga and +1 Altina. Here are the builds I have in mind (with stat boosts from Naga and Altina):
I have an extra Larum for Disarm Trap and a Festival Xander for Close Counter.
