Shield of the Silver Dragon

Ma’at (AL Admin) said:

Regarding the CoS+2 shield with adventure text adding abilities–”emblazoned with a stylized silver dragon that is the emblem of the Order of the Silver Dragon (see chapter 7). The shield whispers warnings to its bearer, granting a +2 bonus to initiative if the bearer isn’t incapacitated” which is the Guardian minor property.

The bolded text excludes it.

Magic items with adventure text adding sentience or abilities (excluding DMG Minor Property and Quirks)* See “End of Play Session” for how it’s earned.

So it can be kept.
