Forum:Mystic tomato and TT

I have an easy question i hope. During a duel today i special summoned a creature during the battle phase with mystic tomato and then tried to activate torrential tribute but my opponent was adamant in saying that it wouldn't work because it MT's effect resolved during the damage step, so is he right that the timing was wrong or could i have activated TT 71.219.159.202 00:21, 3 May 2009 (UTC)
