[@1Charak2] Just to make sure I'm understanding that new rule properly. As long as you control an extra deck monster in your extra deck zone, you can summon other monsters of the same type that are a lower rank or level than that monster, in any other monster zone?

What happens if the card in your extra deck zone is destroyed? Are all your other extra deck monsters destroyed or returned to the extra deck as well? Or do you move the next highest level monster to that zone?
