Forum:Ojama Knight's Effect

I recently had a duel on DN, and my opponent used Instant Fusion to get out Ojama Knight and blocked 2 of my monster zones. In the End-Phase, he gets sent to the graveyard, but my opponent claims that the effect stays active even after leaving the field. I was sure that this is not true, so I showed him the ruling page. He was not convinced because this point is made under "previously official rulings". Who was right now? I am pretty sure I was right, but I just want to make sure. --BronzeJohnson (talk • contribs) 09:02, August 22, 2013 (UTC)
