Yoda and Maul officially confirmed, with Yoda being the first character without any blanks on his dice!

Yoda is going to be a "Interesting" chracter. The fact he has no damage but if you leave him be and he gets lets say 2 Force Meditations on him thats a possible 6 card Mill from Yoda. Maul is a roll in response character. Opponent rolls Qui Qon gets 2 melee and 2 shields, you roll and get both 3/1 sides. Either They remove one of Mauls dice, which removes one of theirs, or they end up taking 6 damage, 4 if they decide to resolve the Shield die. He basically forces certain plays from your opponents depending on what his dice are showing.
