Just curious, say something like Naturia Beatdown with Kaiba or Magnet Warrior Last Gamble with Joey. What about the other minor characters like Odion, Ishizu or Bakura?
Odion: Chain Reaction Burn
Ishizu: No mortal can resist psychic
Bakura , Dark Necrofear deck
Mako , Hammer Shark deck
It really varies. Field spell skills obviously are going to get you to use certain kinds of monsters but other abilities may be a lot more versatile. Labyrinth Builder for example can be used in literally any deck to keep you from bricking first turn.
