I've been thinking about giving some premium skills to Titania, and last night I got a second easter Idunn to give Sturdy Stance 3.
I don't think I really need guard in both phases. Her primary role is to survive ep and then kill next pp. Here's a couple ideas I've been toying with. Not sure which one I like better.
1) Deck Swabber+ and insert B skill here
2) Huge Fan+ and Lull Atk/Def
