Rivalry

Read Genesis 28-30

Genesis 30:15 "And she said unto her, Is it a small matter that thou hast taken my husband? and wouldest thou take away my son's mandrakes also? And Rachel said, Therefore he shall lie with thee to night for thy son's mandrakes."

Whether the clash is between siblings or sworn enemies, rivalry is a good way to show conflict. One object and two people who want it.

Subplots might include the rivals joining forces against another enemy or negotiating like Rachel and Leah did. Stir in some mirroring situations, maybe a dash of comedy.

 

Add dire consequences to each party not getting the item, determination to win at all costs, and mistakes made because of increasing desperation and the rivalry plot nearly outlines itself.
