Bant Control is loaded with Force of Will, Force of Negation, Spell Pierce, and Leyline Binding, so our own Force of Negation is essential to counter their noncreature spells on their turn for free. Brazen Borrower gives us a flash flying blocker against Quantum Riddler or Tamiyo, Inquisitive Student, plus its Adventure side can bounce a problematic Leyline Binding to free a locked-down permanent or reset their tempo. Fatal Push is weak here since their creatures (Quantum Riddler, Solitude) often dodge mana value 2, so we trim one copy; Personal Tutor comes out since this is a durdle-heavy matchup where we want more interaction to survive to our combo turn.
