Cards to Proxy in Type 4?

I am probably going to make a type 4 deck with proxies at some point. One of the real advantages that I can see to this is that I get to play with some hard to find cards. What cards don’t get played much in type 4 decks (if you aren’t proxying cards) because they are hard to come by? This could either be expensive cards (like Illusionary Mask or Chaos Orb) or just cards that no one has (Headstone, some cards from Portal sets).

My list of cards that would be too expensive/rare to play with in a normal type 4 deck but work with proxies is as follows:
Unique cards:
Shichifukujin Dragon
1996 World Champion

Old cards:
Ancestral Recall
Chaos Orb
Illusionary Mask
Forcefield
Ali from Cairo (even though the easily accessible Sustaining Spirit from Alliances is a slightly better card, he’s more classic)
Mirror Universe
Moat
The Abyss
North Star
Pavel Maliki
Tetsuo Umezawa

Hard to track down Portal cards:
Zodiac Dragon
Overwhelming Forces
Devastation
Fire Dragon
Brimstone Dragon
Sun Quan, Lord of Wu

Cards you might not have, even though they aren’t that old or that rare
Infernal Denizen
Headstone
Dwarven Catapult
Reflect Damage
Winding Canyons
Aura Mutation
Binding Grasp (if you need another control magic effect)

Let me know what you think and any cards you’d add to these lists. If you have experience playing with some of the less played cards on this list (Zodiac Dragon, for example) feel free to comment on your experience with them.
