My best accident ever?

I guess he didn't think I had a second Gandora in my deck or able to summon it in the same turn. I forgot how monstermorph works and wanted to see if I could use it on my own Gandora to summon my 2nd Gandora permanently.... it caused him to flip his windstorm early and blow it on my little "test". Glad I decided to get experimental, otherwise I think I may have lost if he summoned anything the turn after he would use a proper windstorm.
