The exact value is hard to figure out, but its likely that now after wearing it and spending so much on it, Paul could try to sell it for more, inflating the price of the card in the process
When a card shows part of an adjacent card on one edge meaning you can see artwork or border from the card that was next to it on the uncut sheet that's a significant miscut
Id likely go with a mana engine such as Phyrexian Altar, and then add things that bring extra value
Otherwise, these values seem fairly stable
For example, you may play a land only during your main phase while the stack is empty
The decks also helped the set feel like more of a return by bringing back an element players wanted which couldnt fit in the main set proper, much like the precons for Lost Caverns of Ixalan
