Odric, Lunarch Marshal

If one of those creatures has one or more variants of the listed keywords (for example, hexproof from white), creatures you control gain those specific variants.

Multiple instances of any of the abilities Odric can grant your creatures are redundant.

Odric's ability triggers at the beginning of each combat, not just combat on your turn, whether or not any creatures you control have any of the listed abilities. If a creature gains one of the listed abilities before Odric's triggered ability resolves, perhaps due to another ability that triggered at the beginning of combat, then creatures you control will gain that ability.
