Thracia Banner Worth Pulling for me? Also summoning Plans for the future.

I'm a F2P player and I currently have 23 orbs.

On the Thracia banner, I have a 4.50% Appearance rate currently. The units I want are Nanna and Olwen, but Leif or Master Sword Reinhardt would also be nice to obtain as well.

However, I have a few things holding me back from pulling.

I do have a bunch of healers like Priscilla, Elise, and Bride Lyn, but Nanna will be very useful to have in the back since Restore+ is applicable everywhere and I tend to use my horse healers a lot.
34 speed is nice. I wouldn't say she's better than Elise, but I still want to get her.

In the case of Green Tome Olwen, while I do have Cecilia and Guunthra with Blade Tomes inherited, I like running a TA raven build on Cecilia and I like the uniqueness of playing with Guunthra's Blizzard. Green Tome Olwen has a legendary Blade tome so since she is technically cheaper to build and she also comes with Swift Sparrow. Her offensive stats are also excellent. 30/35 offensive stats are pretty good.

Leif's stats are nice and S drink is pretty good for Tempest Trials and Chain challenges. Also, Light Brand is a interesting sword to try out. However, I have so many good sword units already like Ryoma, Lucina, and Zelgius.

Master Sword Reinhardt is definitely unique and strong, but like Leif, I already have a ton of good Sword horse units like Siegbert, Sigurd, Brave Roy, and Xander that I actually don't necessarily need him. I feel like he's over-hyped just like Sigurd. Don't get me wrong, he's great, but he's not totally game-breaking at least in my opinion.

Finally, I have a strong feeling for Golden Week, we will be getting the Choose Your Legends 2 units (Veronica, Celica, Hector, and Ephraim) and I'm VERY interested in seeing what they are bringing to the game.

Any thoughts on what I should do? Please let me know! I'm still getting used to saving orbs as a F2P player.
