Races with Longsword Proficiency?

[jaappleton]

What am I missing?

Githyanki
Eladrin (DMG)
Hobgoblin
High Elf
Wood Elf
And the Half Elf variants of Wood and High Elves

And I suppose VHuman with Weapon Master.

Anything else?

Since you included Eladrin from DMG, which is technically only a "suggestion" of how the race could be done and somewhat equivalent to Unearthed Arcana, I'd say Plane Shifts are likewise compatible

Plane Shift: Amonkhet
- Khenra (PS:A specifically says you treat Khopesh as a Longsword)

Plane Shift: Kaladesh
- All elves

Plane Shift: Zendikar
- Joraga and Mul Daya elves
