Forum:Creature Swap Help

Okay... so I control Mother Grizzly and my opponent controls a monster. I creature swap and attack Mother Grizzly with my opponents monster. Mother Grizzly is then destroyed. Do I use the effect of Mother Grizzly or does my opponent use it? Do the effects of the monster that was swapped carry on to the opponent? Thanks! DNA25th (talk • contribs) 22:25, June 17, 2016 (UTC)
