Apparently Andrew Cuneo was the first team member to discover the power of Tolarian Academy, with a deck featuring "all eight Baubles" powering out Mahamoti Djinn
Versatility & Ubiquity: A card's strength can be measured by how many different decks and formats it appears in
For example, casting Cerulean Wisps on a creature will turn it blue, regardless of the color chosen for Painter's Servant
In many cases, theyll be willing to look through a small collection or stack of cards and give you a price on the spot, though at a discounted rate from the total expected market price
It has a reasonable downside of having to put a card from your hand on top of your library, being able to stop all damage from an instant or sorcery
Hopefully blacks ability to kill enchantments stays flavorfully linked (because surely they will eventually desire to push the boundaries and make a non-Edict style spell, again expanding the range)
