Extra S!Y!Tiki off 1st circle then pass on Legendary Banner

Wondering which units might benefit most from Atk/Def Bond. Also I have a W!Robin that I'll probably never use (I rarely use my B!Hector or W!Ephraim as is and I'd use them first) wondering if I should fodder his Brazen, Armor March (likely to W!Cecilia), or his lance?

If it's his lance the only unit that really comes to mind for me, since Catria now has a prf, is our upcoming free TT NY!Laegjarn? Could technically even pass Brazen Atk/Spd 2 from 4* Linus first to get both the weapon and the Brazen for her. Other than that I have Lucina and Summer Linde already with Brazen Atk/Spd. And I'm content with +atk/-spd sword Lyn sticking with Brazen Atk/Def.
