Phantom Carriage is an excellent one for finding whatever card you need at any given time, so should definitely be in the deck
Alongside Okidogi ex SFA 90, Munkidori ex SFA 91, and Fezandipiti ex SFA 92, it forms a unique "mosaic", created by the wonderful artist kantaro
Team but found that it was a little too hard to do and the payoff wasn't equal to the difficulty
Setting aside the utterly random bit of artifact-hosing (which I guess is a reference to Mirrodin Pure defeating the colored Phyrexians), theres an interesting riff on cards like Platinum Angel, Lichs Mirror, Angel of Grace, and Exquisite Archangel
These sets have tons of cards with unique names, meaning the sets have a much lower number of reprints, even if they have similar abilities and effects
