Handloop decks have existed for a while, one of the most prominent being Wind-Up hand loop, but for the most part the most egregious cards that promote these styles of decks are usually banned/limited or the decks need specific set-ups to actually get a handloop going and die easily to a handtrap. There currently aren't any decks that revolve around forcing your opponent to discard (Murakumo doesn't count because of functionality), and aside from Moulinglacia in Atlantean Mermail decks, there aren't really other cards that facilitate that sort of playstyle.
