Forum:Dupe Frog Lock down?

I am having a hard time understanding, a few things. First, and foremost how does the Dupe Frog Lock work, I never understood that. I don't get how having two Dupe Frogs on the field, prevents your opponent from attacking. Could someone please explain that to me.

I understand that Dupe Frog's effect makes your opponent attack it, what I don't understand is how does having a 2nd Dupe Frog lock out your opponent's attacks, regardless of how many monsters he has on the field. And, would the same thing work in an all warrior deck with 2 Marauding Captains on the field, if so how does that work, I would assume that it works the same way as Dupe Frog x2 on the field, along with Morphtronic Magnen x2 but then again the whole process confuses me.

Could someone help me to understand this?
