Jeskai Control has almost no early creatures to interact with, so anti-aggro pieces like Lodestone Needle and Dusk Rose Reliquary are dead weight here. Page, Loose Leaf gives us cheap, resilient artifact threats that can go under sweepers like Day of Judgment and Deadly Cover-Up while providing card selection through Grandeur to dig for our own threats. The extra Tezzeret, Cruel Captain is a strong grindy planeswalker that generates recurring value and pressures their limited number of answers. Keep the core artifact-matters shell intact since it out-values their card advantage engines like Jeskai Revelation over a long game.
