Beanstalk Control is a grindy value deck built around Up the Beanstalk, Tamiyo, Inquisitive Student, and Murktide Regent, protected by its own Force of Will and Force of Negation, so matching their free countermagic with an extra Force of Negation helps you win the long game. Pyroblast provides efficient interaction by countering their blue spells or destroying blue permanents like Tamiyo, Inquisitive Student and Murktide Regent. Phyrexian Dreadnought trades poorly into their Swords to Plowshares-heavy removal suite for a two-for-one, and Curie, Emergent Intelligence is too slow against a deck built to grind with card advantage, so both are cut for interaction and pressure.
