Their playstyle revolves around replacing your opponent's rear-guards with Grade 0's from the Drop Zone or Deck in order to weaken the opponent's field and prevent intercepts (if the front row is replaced) as well as decreasing the amount of triggers in the deck and Drop Zone. Certain units also capitalise on the opponent's weakened field and decrease the opposing Vanguard's power (Witch of Quests, Securna and Cultus Witch, Rias). One could also say that their playstyle resembles a witch's curse.
