The solution for fixing bad decks has never been giving them a single card that reads "If you negate this I am literally going to fucking kill myself", there's kind of an obvious reason why the meta decks of the format has every card basically summon themselves and search and decks like Springans or Genex or Jurrac are relegated to obscurity, giving decks competent engine pieces in the form of powerful starters and extenders, alongside payoffs if they're lacking in them has always been the more effective solution
