Use "any zone" in place of a list of all locations

[thirdpolice]

For example, https://commanderspellbook.com/combo/25076/ has the prereq "Civilized Scholar // Homicidal Brute in hand or on the battlefield or in the command zone or in exile or in your graveyard or in your library."

The preferred text for a starting location prereq with every box checked is "Civilized Scholar // Homicidal Brute in any zone."
