Nibelheim Aflame was my other "this must have flashback" design
Unfortunately, while the contents of the Final Fantasy Secret Lair was not only heavily sought after, but a great deal reprint-wise, which is rare for Secret Lair, the sale was an absolute disaster, and Scalpers are part of the problem
It has both pivotal lines of text that you need to make a true wall/defender deck work, inverting their damage based on toughness, and allowing defenders to attack
If the activated ability's cost contains a choice, such as a creature to sacrifice or a number of counters to remove, the copy created by Vantress Visions uses that same information
I drew my copying playing Draconic Domination and the scry trigger was invaluable for keeping the gas flowing
