The rules of Pixel Tactics have been updated. You can read the new version here.
Don't download the PDF from the link above, as the PDF rules are still the old version.
This is what the updates rules say about Ongoing Orders:
Updated Game Rules wrote:
Some heroes in Pixel Tactics 2 and later have “Ongoing Orders”. These are marked by a scroll symbol.
Ongoing Orders can only be activated from a player’s hand–they have no effect when triggered by another effect, like the Puppeteer, Mascot, or Doppelganger.
An Ongoing Order is placed behind the back row of your board, and there are 3 slots for currently ongoing orders. Turn the order 90 degrees at the end of each of your turns, including the turn when you play it. When it would be rotated a 4th time, it is discarded to your discard pile instead and stops working.
Yes, they work until the end of the round.
EDIT: Ooh, they don't!
