Forum:Fissure, Fires of Doomsday, Torrential Tribute

I was playing against my friend and had out a Tempest magician and one face-down monster. I have a Fires of Doomsday set, and he has a Torrential Tribute set. During his turn he plays Fissure from his hand, and I respond with Fires of Doomsday. He then tries to Torrential from my tokens coming into play. I claim that he misses the timing since he can't add Torrential to the chain since nothing has been summoned yet, and since Fissure will resolve immediately after Fires he will miss the timing for Torrential. Can he activate Torrential or not?
