I noticed the rules for backing your harvesters and border keep have been expanded to note that if they try to enter the dynasty deck, they can. This explains why they must be backed the same way as the respective dynasty deck.
However I also notice that all the harvesters I can find, have green fate backs (or identical to the front backs) so they can't go in decks. If playing with the deck out of the new EE starter decks, what happens if a card that puts a holding back in your deck is played? Doesn't this make the EE starter decks illegal to play?
An example, Grasp the Earth Dragon will grab a holding out of your discard pile and put into your deck. With the EE starter decks if the targeted card was a destroyed bamboo harvesters, it would work.
