I have a question, if a player would have a boardstate of Sundial of the Infinite, Smokestack, Trinisphere and 2 basic lands he will never have to draw again, but the question arises if their opponent is playing an Emrakul, the Aeons Torn, he might never get to play a spell but he can not deck himself (by discarding the Emrakul at EOT). The person this discussion came up with made the argument that player 2 is not allowed to discard the Emrakul because it would cause a fragmented loop (assuming they have no way to deal with smokestack + sundial) My opinion is that they game would either be called a draw or that activating the sundial is the cause of the loop and thus player 1 would not be able to activate it.
