This is mostly a question of timing. In advanced mode Voss gets an extra card play at the end of turn. This of course becomes start of turn with Sub-Zero Atmosphere. Thus when it played a forced deployment it triggered immediatly since it was start of turn. if there was ten minion in the trash would that mean:
A: immediate defeat because you've been overrunned or:
B: has the condition already been checked meaning he simply doesn't flip back and immediatly win at that point since it was already checked up and false when it checked up
B, Voss' flip check is listed on the card before the playing a card, so it is checked first.
Voss's win condition, because it is a Start/End turn effect and in play before Forced Deployment, gets checked first. It doesn't re-check until the next round.
B. All checks go in the order in which they are written on the card. So you would have 1 more round in which to defeat the minions before overrun happens.
edit: round, not turn.
edit2: RONWAYD AGAIN
McBehrer is the sole winner of this game... And McBehrer, I would step carefully should you find your way down dark alleys. More than one vote said simply, "McBehrer must die."
McBehrer confirmed to be Biomancer!
