I'm thinking only to display these when rendering the card embed in Simplified Chinese (zh-CN) and omit otherwise, kind of like how Speed Duel limits are not displayed for CJK locales. This means that basically nobody will see this data though, so I'm open to other possibilities. It will probably be too cluttered to include every variation in the Limit line. See also #456
