Forum:A possible OTK?

What if I Have a face-down Morphing Jar 2 that has been set previously then I summon Grinder Golem then I attack with my token letting me take 3000 battle damage as a combo to activate Inferno Tempest, I flipped my morphing jar 2.

question:does my opponent picks up cards until he can search a monster? because he has my grinder golem? resulting him in a deck out? and me leaving me to search my returned morphing jar 2? or is there any flawed?please help and reply
