Don't want to be trying out cards for CubeCon. Replaced with old reliables. List now completely matches paper for the event.

I should be able to get real versions of most of these proxies by CubeCon 2024, but I needed to replace them in the meantime and have a solid list together with no proxies.

Replacements aim to replace with a similar effect or support the same style of deck or archetype. Most proxies replaced are non-essential (PTK creatures, Mishra's Workshop, Volrath's Stronghold, Candelabra of Tawnos, Power Artifact) or enough other effects of the style are already in the cube (Imperial Seal, Ravages of War). Most I haven't acquired over the years because they have never been main-stays in the cube. The only one that doesn't fit this bill is Library of Alexandria. It isn't absolutely essential, but I will try to acquire or borrow it for the event.
