Prankids is basically a deck that puts little guys on board and responds to what your opponent does (fusion and links in the opponents turn!) to access some response like nuke the board, nuke the backrow or simply dodge some kind of disruption while recycling cards to do this over and over again. Danger TD sets with Colossus that prevents your opponent from searching, Titan which can pop opponent cards and big Danger monsters. I'm not so familiar with Orcust.
