This, imo.

Add: The one caveat to this would be the oversized cards. Perhaps those should be made separate from the regular cards i.e. Animar, Soul of Elements - Oversized.

FYI
banefire and etched monstrosity foils not pricing

Puppeteer Clique Foil, Spellskite Foil are both not priced. Also Ojutai's Command (Prerelease Promo) and Hidden Dragonslayer (Prerelease Promo) have no prices, didn't know where else to post them.
