I am trying to remember a certain card, I need it to try out a combo. It is the continuous trap card that changes the type of all monsters on the field. I just need the name of the card, because I am having trouble trying to read through all my commons looking for it.

If it's the type, then it's DNA Surgery. There's also another trap that changes the attribute of all monsters, and that one is called DNA transplant.

DNA Surgery is the one I was inquiring about. Thought it would be interesting to mess over some guys who think they are hot stuff with a useless off the wall deck, going to DNA surgery their monsters to machine and then limiter removal them to create an effect almost like torrential tribute :p

Oooh, very tasty indeed! I had an Archfiend/Machine hybrid that worked pretty nice along these lines. I used target negation of Archfiends and fused it with the attack power of machines. I tossed in a Heavy Mech Support Platform for some non-targeting protection and System Down became really nasty against my opponents 8^D It was quite fun.

You could also do something similar by DNAing the field to fiends and then using Goblin King for a massive beater or Exile of the Wicked to flush everybody out.

The only problem is that Limiter Removal only effects the users monsters. but System Down would probably work.
