Air Shaft: Third Junction

The Air Shaft: Third Junction location is functionally identical to a regular Air Shaft, with a few notable exceptions.

First, unlike regular Air Shafts, it is a shared location: one player's Air Shaft: Third Junction is the exact same place as the other player's. Second, only one copy of the card may be played on the same 'between-deck' line. This is to say, if one player has already connected his Air Shaft: Third Junction between decks B and C, the other player, if he chooses to play the card, must connect it between decks A and B. In this way, the Air Shaft: Third Junction becomes a 'vertical' location, enabling a unit to get from A-Deck to C-Deck, and vice-versa, without ever leaving the shaft.

Finally, the Air Shaft: Third Junction has a restriction that it must connect to another Air Shaft, and only another Air Shaft may connect to it. Thus, unlike regular Air Shafts, it may not connect to a Ladder.
