Note all queries are limited to 400 results.
NOTE: The Alternate Location field is meant to show the best alternate location to find a card. I do not list every location that each card can be found (otherwise, Dark Hole would be listed dozens of times since everyone uses it). Rather, I note which Challenge deck runs the most copies of each particular card. So if you see a number in parenthesis, that confirms how many copies of the card can be found in that Challenge Deck. If you do not see a number in parenthesis, that means I have not yet confirmed the number of copies used in the Challenge Deck as that info is slowly being updated.
