Careful use of "Zero Gravity" and "No Entry!!" will allow you to manipulate how your cards are destroyed. In the event of "Dark Hole" or a similar field clearer, you can chain either of those two to put all of your monsters to Defense to protect them from destruction, and in the event of a giant swarm, you can activate either of those two to disable their attacking while making sure if the opponent has a card like "Elemental HERO Wildheart" they still can't take out a monster on your side of the field.
Use "DNA Surgery" to convert this card into one of the three types it's effect affects. affording this card self defense via its own effect.
