Silverfish重构【2】-限制惩罚为某一behavior特有

        public virtual int GetSpecialCardComboPenalty(CardDB.Card card, Minion target, Playfield p)
        {
            return 0;
        }

            int retval = ai.botBase.GetSpecialCardComboPenalty(card, target, p);
            if (retval != 0) return retval;

        public override int GetSpecialCardComboPenalty(CardDB.Card card, Minion target, Playfield p)
        {
               //在这里写你的惩罚，格式和penman一样
               return 0;
        }
