Here is a situation needing adjudication...
I have a Lost Soul sitting in a red site.
My opponent has The Ends of the Earth in territory (actually sitting on the divider between territories in RTS), brings the NT Gabriel into battle and declares RA. TEotE is the only possible way Gabriel could have access at this point.
I block with Zimri and discard a Crimson enhancement to discard all cards in battle.
My opponent discards Gabriel but leaves TEotE in territory. I ask him to discard it and he says it was never in battle.
OK. So before I blocked, I could have asked how exactly Gabriel had access for an RA and forced my opponent to explicitly bring in TEotE. The question is, in the situation above--do I have to ask my opponent the question--or is his declaration of RA sufficient to assume that TEotE was in battle?
Second related question--my opponent claimed that you can bring sites into and out of battle as you desire. While I understand that at any point (with or without initiative) you can add a site to battle, the REG says,
Site access cards in battle may not be removed prior to the battle resolution unless forced or allowed by another card.
Doesn't this mean once a site is in battle it stays in battle until the end (or an SA removes it)?
