Forum:Mermail Abysslinde and Mermail Abyssdine

My friend was dueling someone on Devpro. He was using Mermails and it was his opponents turn. His opponent attacked and destroyed his Abysslinde so he then used Abysslinde's effect to special summon Abyssdine but he was not able to activate Abyssdine's effect special summon Abysslinde from the graveyard. Was what my friend was trying to do an illegal move or was it a legal move and their was just a bug on Devpro?--HEAVYMETAL117 (talk • contribs) 06:09, July 26, 2014 (UTC)
