It manipulates the Monster Type on the field which certain themed decks may benefit. E.g. Declare Thunder-Type then use Makiu, the Magical Mist and Declare Dragon-Type to increase Buster Blader's attack.
Your opponent might be running a deck that benefits with the Monster Type that you declared.

Destroy them all!
Declaring all monsters into a certain type, will allow you to use cards that destroys all monster of that type. Cards like Eradicating Aerosol and Breath of Light are examples of such cards. It's important to remember that using these cards will also destroy your own monsters.
There are a lot of potential combos by using DNA Surgery, but its main problem is that you can only obtain 1, and getting it early in a duel can be a problem. You can get 2 copies from leveling Ishizu, which can be used to get DNA Surgery from your deck easier.
fusion,synchro,xyz,and potentially link is a "kind". and that is an official term used on sacred serpent's wake. later on they are referred as "type" on the effects of cards like invincibility barrier and inspector boarder. there are "subtypes" that are written the monster type. how are people confusing secondary types with monster types is beyond me btw
btw primary typings are officially called "monster type" while the other types listed after that; effect,flip,tuner,spirit,link,toon etc dont have an official term unless you count sacred serpent's wake referring to fusion synchro and xyz as "kind"
Probably, it seems like a good skill to play with this card.
I saw this broken piece of crap on a Platinum replay today. It destroyed an optimal Koaki deck. No level 3 weakling monster should be able to become a 3300 attack God against every single monster. This card needs to die.
Kinetic soldier deck vs buster blader deck. I let him resolve his dna surgery first calling dragon, I had the option to chain mine but common knowledge I decided to use mines after so mines would replace his. He fusion summons dark paladin, I use my dna surgery calling warrior, and he still got the boosts cuz all the monsters were still dragon. My Soldier didn’t not receive a boost either, so his dna surgery was still in effect. Is this an error in the game?
I think this card could be a key player in defeating plant decks. Because any effects of plant monsters traps and spells relies on plant type monsters, so when you change the type of all monsters on the field it could be a quick way to cut those plants down to size!
