What to do with Sorcery Blade?

And why would DC be required, mages normally have low def and too many people take -def when -res would be the best choice bulkwise, it's very unlikely you will go against a mage who has higher def than res

It might be good for units that often focus on enemy phase units, and don't need the A slot for stats.

Lukas comes to mind, if he runs a slayer lance with close def seal (and doesn't need the def) But it's not better than breath.

Another one is OG Takumi. He can easily use the skill in both phases, and is could allow him to take down tanks and mages more easily. (though he still needs team support for his speed)

At least any sword/lance/axe/bow/AND dagger infantry with high atk can use this. Chrom,B!ike,B!Cordelia,Lagault (running cleaner and hitting weaker def/res if target is buffed!? ooof) Sothe, etc. come to mind, so im interested what builds this will bring to the table. Plus this goes well with the bond seal we've just obtained.

I have an idea, with heroic grails making GhB characters better with merges. Why not use it on Lloyd? His regal blade already benefits him with magic units nearby and his average attack can be patched with the skill.
Though the same can be said for Linde and merric, I feel Lloyd uses it best

Fjorm ? Dorcas ? If you want infantry with DC weapon.
I think it's fine on a dagger unit.
Kagami mochi+, this skill, something like blazing wind. 3 Infantry pulse supporter ansd it's a massive special attack on the first fight.
