With the dead teams gaining nothing from winning, they will all target Air. It's not fair on air... I mean, I don't want targets myself, but this seems like it could inhibit a fair result of war rather than simply speeding it up like the previous (very good) EC.
Also, allowing them to use ANY deck from war makes it almost impossible to fully mindgate, in fact it makes it easier for the dead teams than some of the living
Also, how do the living teams decide which deck to use against the dead teams that target them, considering they will only find out at the end of deckbuilding phase?
