Great list! Can't think of ANY to add off the top of my head!

I absolutely adore Mordicus' full-length even if it is way more Swedeath than Finn... :loco:
 
One band you didn't list that is pretty fucking weird Coldeäccol
Funcunt-Mikko Mattila
And not really pure death metal but
Protected Illusion-Festering Fairytales both from Finland and both are great bands.
 
Most Finnish death metal is rather "obscure". I'll just recommend great Finnish death metal in general.

Amorphis - The Karelian Isthmus
Amorphis - Privilege of Evil
Belial - Wisdom of Darkness
Belial - The Gods of the Pit pt. II (Paragon So Below)
Convulse - World Without God
Demigod - Slumber of Sullen Eyes
Adramelech - Psychostasia
Cartilage - The Fragile Concept of Affection
Funebre - Children of the Scorn
Sentenced - Shadows of Past
Sentenced - North from Here
Disgrace - Grey Misery
Demilich - Nespithe
Purtenance - Member of Immortal Damnation
Phlegethon - Drifting in the Crypt
Krypts - Unending Degredation
Lantern - Below
 
Xysma -yeah is a really cool album. It's not pure DM in a sense of other Finland Death Albums, but it still has the elements and worth checking out. Vomiturition -a leftover is one my favs, the Head Tales EP is cool too.
 
I don't know how obscure they are, but Insomnium and Swallow the Sun are some of my favorites. Down with the Sun and Drawn to Black by Insomnium are some of the best melodic-death pieces I have heard, and I'm a melodeath fan in general. Swallow the Sun is a sort of doom-melodeath hybrid, and they sound very good as well.
