Kaza, Roil Chaser turns a board of Wizards into a discount engine — each untapped Wizard reduces the cost of the next instant or sorcery you cast by one generic mana, which spirals fast in spell-heavy blue-red lists. The catch is that Kaza herself has to tap to activate, so she's a lightning rod for removal, and cards like Ghostly Flicker let you abuse her ability multiple times in a turn only if you can protect the setup.

Kaza, Roil Chaser is a Commander card through and through — the ability rewards building around a Wizard-dense, spell-heavy shell, and that kind of tribal-synergy construction is most natural in the 100-card singleton format. In Legacy and Vintage, she's technically legal but competes with far more efficient mana reduction and combo infrastructure; no competitive list wants a two-mana creature whose effect requires a board state to matter. Modern and Pioneer are similar stories — Kaza is too slow and too dependent on board presence to slot into the tempo or combo decks that define those formats. Commander is where she's worth building around, ideally as the general of a Izzet Wizards storm-adjacent list that can hit double-digit Wizard counts reliably.
