I've voted Regis because he is a really cool character in Blood & Wine.
I currently use Dandelion, but quite honestly I always feel a bit silly when I play Monsters with my Skellige Border and then have Dandelion for the taunts. Therefore I would like to see a game option that would allow me to choose between using my avatar or the leader of my current deck for taunting. Not sure though how that would work for Arachas Queen ;-) but you get the idea. The avatar is more a representation of my personality, but the leader is really who eggs on his or her troops in the battle and taunts the opponent. Having it as a selectable option would not force it upon on players either way, instead everybody can select what suits him or her best.
