Anthony has satisfied the trigger condition for Darksteel Reactor. The trigger resolves, and he wins the game. However, with the limited range of influence option, only the person to Anthony's left and right will lose the game. There is now a void on Anthony's left and right, and his range of influence is not reevaluated until the beginning of his next turn. But Anthony never gets another turn because the Reactor will trigger again and again forever.
What happens to Anthony now? Can other turn markers bring opponents into Anthony's range of influence so that they will lose to him? In other words, can the void on his left and right ever be collapsed? If not, has he fallen victim to an infinite loop, forcing a draw by his own victory condition?
