Talk about awesome! I got it done BEFORE Friday
Anyway, this list here is all cards whose FULL cannot be properly displayed by MWS. I make that distinction because if you use a theme that displays one of the unique borders (specifically the planeshift theme) you obviously won't need to use fulls of the Planeshifted cards.
Note that watermarks were not counted so while
Privileged Position (which has a hybrid cost) makes the list,
Selesnya Signet (which only has a watermark) does not. This also means FNM and ARE are also not included. Finally, since Elves vs. Goblins and Jace vs. Chandra (and eventually Divine vs. Demonic) only come in fulls, I also left them off the list.
If you would like a list of cards with watermarks (I'm not going to do one for FNM or ARE) I can do it. It's pretty easy since only RAV, GP, and DIS are the only ones besides promos with watermarks.
Below is a list of what the codes (identified by the set they appear in) means. There are exceptions, the five planeswalkers of Alara are in their sets, and
Reaper King is in SHM (he does have a hybrid cost!)
CHK, BOK, SOK = Fulls that use flip borders
RAV, GP, DIS, SHM, EVE = Fulls that use hybrid borders
PLC, FUT = Fulls that use plane or future shift borders
LRW = Planeswalker border
ALA, CFX = Colored Artifact border
UG, UNH, CHP, REW = cards that use a unique border
