Forum:Future Fusion usage

Hey, I need to solve a conflict. Someone I was dueling used Future Fusion, and then later used the exact same future fusion to fuse another monster, while the future fusion was on the field. He tried claiming that "it can be used more than once" and quit after I destroyed it. Is it legal to use future fusion's effect more than once? Lugia61617 (talk • contribs) 08:15, June 12, 2011 (UTC)
