Will my New Tank NOT Cycle if I only use Dry Rock (Marco Rock)? trying to avoid Cycle

So I am planning on upgrading my 10 Gallon Aquarium to a 30 Gallon Frag Tank (30 X 18 X 12).



People keep recommending Marco Rock.



It is Dry Rock though and not Live.



But you do avoid any Hitchhikers and it is Cheaper.



My Question is if I use Dry Marco Rock Only.



Will I avoid a Cycle (No Ammonia, Nitrite, or Nitrate)?



Also, how long will it take for the Dry Rock to become Live Rock?



Don't you have to add at least one piece of Live Rock to seed the Dry Rock and transfer all the good animals that are in Live Rock?



I mean I do not see how this stuff would Magically appear.
