I've been running this team in Arena for the past few months: Fae, Nowi, Olivia, and a askr unit as a bonus. When Olivia is bonus, I put in Reinhardt.
I'm planning to get as many 5* merges as I can. My Olivia is 4*+10, so naturally I'll need a solid 5* replacement that I can easily merge. Preferably a red replacement to deal with Julia/Deirdre. My options are:
1. Adult Tiki - Meshes well with Fae and Nowi + easy counter for Naga mages with TA3. Downside is lowish BST compared to Fae/Nowi which hurts scoring.
2. Eliwood - Legendary weapon helps out with scoring and cavalry range allows him to rush up and shank Naga mages. Alternatively I could put Distant Counter on him to make him into a somewhat competent anti-magic unit.
3. Draug - An odd choice but his very high BST helps a lot with scoring, but I don't think he'd mesh well with Nowi and Fae and couldn't easily take down naga mages.
What do you guys think?
