It's part of the 'Lighray' archetype. 'Lightray'/'Lightsworm' decks rely on discarding cards from your deck/hand to special summon big monsters like Diabolos or Judgement Dragon(personal archnemesis) to achieve REALLY easy OTKs. Even easier now considering that we have only 4000LP. On DuelGeneration (another yugioh game for tablets) almost everyone used that deck before pendulum became a thing.
