All artifacts have "At the beginning of your upkeep, sacrifice this artifact unless you pay ."
Kataki is a mono-white stax commander: cheaply tax every artifact in play so opponents bleed mana or sacrifice their mana rocks, treasures, and equipment while you run a near-artifact-free creature deck that punches through unimpeded. You curve out into hatebears and tax pieces, lock the table out of acceleration, then close with efficient white creatures or token swarms.
Add more low-curve white disruption like Drannith Magistrate, Aven Mindcensor, and Leonin Arbiter to turn the deck into a true prison, and lean on nonartifact ramp/draw such as Land Tax, Esper Sentinel, and Smothering Tithe to fuel it. Tighten the wincon with anthems (Intangible Virtue, Skullclamp draw avoided—stay artifact-light) and a finisher like Elesh Norn, Grand Cenobite to slam shut a board you've already starved.
