Either go for:
Raven tome build(she's really good at using it and she has the def to use it well )
OR
Blade tome(cause emblem buffs are too op and since she has +spd, she can double.)

with a speed boon she can effectively run gronnblade with darting blow if thats something you're into but otherwise, her ravenadept build is her best and the res is patched up with triangle adept and greentomebreaker

She can run both Raven+TA and Bladetome sets. Even with -Res, she can still tank Reinhardt. If both B!Lyn and Reinhardt attack her consecutively, she can destroy both of them if she has Vantage and it doesn't matter which of them attacks her first.

Because you got a +Spd IV, her Bladetome set is very much viable with Darting Blow+Desperation since you will need to power up her tome with Hone buff anyway. If one or two other fliers also has goad fliers, she'll reach very high doubling potential. You can also use a defensive Bladetome set too with Vantage. If she gets all 4 stat buffs and she's in Vantage range, she can bait and destroy most units. The premium set with that is having Close Counter so she can bait melee units as well.

Congrats on the Super Boon.
With a her IVs she can run the Bladetome, LnD and Desperation.
With Hone Fliers she'll reach 54 Atk and 40 Spd.
Just make sure she's not in range of mages before the enemy phase.

I personally run the raven tome on her and I don´t regret it one bit. Gave her iotes shield in the seal slot and now she´s the one that can take care of bows, which is flier emblem´s biggest weakness. Since b!Lyn is so popular in arena ( reinhardt too) it´s very important to have a counter for that.

Bladetome is also really good , especially with a speed boon! Give her darting blow in the a slot and with honefliers she can deal out a lot of damage!
