Depends on what deck style you like most and on your budget.
Corruption Mages utilize
Vital Syphon and
My Name Is Legion as key cards and Nehant Guemelite mages in order to maximize
My Name Is Legion. Since Legion is pretty expensive, for budget deck you can consider
Corruption of the Soul as damaging spell.
Some of more useful spells are
Magic Sensitivity,
Perversion,
Nehantic Hold,
Desolation of the heart, etc.
Hand-deny Marauders go for denying draw and returning enemy's hand to their deck.
Characters are
Utkin, Nehant Kid,
Shadow, Lady of Nehant and
Torment or
Hate.
Key cards are Cutting All Ties, Illumination (it is important that 3x Cutting are ONLY spells in deck),
Hesitation,
Paranoia,
Blackness which turns into nuke combined with
Dismemberment.
Demon Warriors rely on
The Scourge Of Souls ability to negate damage from items and is great filled with items like
Pestilence Perfume,
Captain's Hipflask,
Cursed Black Armor,
Cursed Black Dagger,
Corruption Rosary and other cursed items. Has decent direct damage with
Lords of Ruin,
Blackness and
Dismemberment.
Debuff-Servant Warriors are pretty cheap deck which goes with
Gnarl,
Ripper and 3rd character, maybe Ardrakar for her defense boost. Ripper gets stronger as Servants enter game, and deck can heavily cripple enemies with use of
Bile Spitter,
Demonic Ax,
Black Chimera,
Chalice, Nehantic Blade,
Corruption Rosary, etc. Cards like
Demonic Explosion or
Dark Ritual which depend on number of Servants are good addition.
Hope this hels ^_^
i was just playing with random characters and had no idea which to actually make a deck around
