Is this the EO?
whitehouse.gov/presidential-actions/2018-amendments-manual-courts-martial-united-states/
If it is the one named "Executive Order Blocking the Property of Persons Involved in Serious Human Rights Abuse or Corruption" - looks like it is Executive Order number 13818, per treasury.gov/resource-center/sanctions/Programs/Documents/glomag_eo.pdf
But this is not my field of expertise.
BTW, thanks for your work on the cards.
