cavil's ability allows him to remove a basestar if there are two on the "game board" but since his card was part of the pegasus expansion, it isn't clear how it interacts with exodus and the cylon fleet board.
should his ability only work if both the basestars are on the main board? either board? if one is on the main board and one on the cylon fleet board, should he be restricted to only removing from one board or the other?
