Xion II

You can't have a second copy on board.

In your own watch, while this card is in your scrapyard, you may pay the cost to put it on board. It isn't deployed: no one can react to it.

Exhaust it to use it. A token is a card an ability makes (301.4). It is deployed like a crew card, at no cost: into the crossfire, where the opponent may react, or straight on board when no one can. It stops existing when it leaves the board. Only in your own watch, with the crossfire empty; it resolves at once. A base can use it in the turn it comes on board (307.4).
