Thanks! At least, that will show me how it should be, by set, regardless of coding. It is odd, though. Would be curious to hear from AW on it.
If anyone was curious, the codes usually follow a rubric: MW leads for Mage Wars, followed by a set identifier (e.g. AWD for Academy Warlord expansion), followed by a letter code for card type (e.g. Q for equipment) and a number. This is on the bottom of every card, including promos. So the Commander's Cape from the Academy Warlord expansion would be MWAWDQ01. Useful for sorting, organizing, and helps you confirm you have everything you are supposed to have in a box, because they are ordered.
