I was just wondering if Shaggydogs ability (Kneel a Direwolf card to choose 1 attacking character. Until the end of the phase,that character gets -2 STR) can interfere in a challenge between 2 other players in a melee game.
E.g. Player A attacks player B with a Strength of 8, and player B defends with a strength of 7. Can player C kneel a dire wolf to lower the stength of player A's character causing B to win the challenge?
