If aesthetics doesnt matter:
Top: LTD Valk expansion head gear OR specialty headgear (cards are subjective to build/skill if you need bijou or kiel cards)
Mid: Debatable due to recent update. any LTD emperium aura would be a safe option since it is an all around aura (cards are subjective to build/skill if you need bijou or kiel cards)
Lower: Blessed/Cursed/Guardian variant (Ring, Slayer sword, Scarf, Ribbon, etc.) It also depends what skill you will use (cards are subjective to build/skill if you need bijou or kiel cards)
Armor: Dragonist Armor (Class specific ex. Champ DA, LK DA). You will need fame for this to function
Weapon: Valk Weapon (Depends on class and build. Champ only has Dorcus while LK has Ullrs, Freyr sword, etc.)
Shield: Friggs King shield. I'd say you would need 2 at the very least
Cloak and Boots: Valk Cloak and Boots
Accessories: Quest Accessories. Depends if you want survivability (blessed) or damage (cursed)
Cards for non-headgear stuff you can browse around in forums or ask ingame. These cards wont cost you as much as 1 of the items mentioned above. I gave you the most expensive card option for headgear(bijou) and I repeat it is build/skill specific.
