Great, to see some information about new cards.
As there were some complaints that it is impossible for players to move their cards away once they are moved by the enemy to one row, I could imagine that Avallach is the counter to that. As he would probably be too similar to Sheldon if he moves untis away from his row and too similar to Malenna and Zoltan, if he moves them to his row, I guess that he will rotate all or a certain amount of cards from all rows to the next one. It will help against weather and furthermore, if different rows become more meaningfull again, it will synergize with that too.
The female druid looks like an adition for the self wounding archetype because of the bear. As she doesn't have much power budget with already 8 points, I guess she will give a small buff that is stronger when the ally is wounded.
The siege machine could be many things. As all NG siege engines so far are part of Reveal, I would bet on that too. Of course it also could deal splash damage to targets around a spying unit, but that doesn't seem to be that kind of siege engine. So, I will settle for, whenever a revealed enemy unit is placed on the board, it will get damaged.
The ale will most likely be some kind of buffing alchemy card. Can't imagine what exact kind, because there are already more than needed in my opinion.
What do others think these cards will do?
