Izzet Phoenix is a fast combo-aggro deck trying to loop Arclight Phoenix back from the graveyard via cheap spells, and this is a race where your top-end finishers are often too slow since they can rebuild board presence for free. Skyreaping is dead here since Arclight Phoenix and Picklock Prankster are their only flyers and your devotion may not reliably produce enough damage against a 3/2 and 1/3, so only include if you expect heavy devotion; treat this as a minor tech choice. Reclamation Sage doesn't have a great artifact/enchantment target in their list, making it also a weak include; if better options aren't available, consider keeping maindeck as-is and minimizing changes. Given the lack of strong sideboard targets, this swap trims your slowest top-end slightly in favor of flexible bodies, but the core plan remains proactive ramp into a quick clock before their graveyard recursion takes over.
