1/1/2011 : If multiple lands enter the battlefield under an opponent's control at the same time, Tunnel Ignus's ability triggers that many times, even if no other lands had entered the battlefield under that player's control earlier in the turn. That's because each ability takes into consideration the other land(s) that entered the battlefield at the same time as the one that caused it to trigger.
