Boros Aggro is fast and aggressive, so a second Day of Judgment helps reset a board that's quickly flooded with Momo, Voice of Victory tokens, and hasty dragons. Rest in Peace denies any graveyard value and also exiles Dragonhawk's flashback-adjacent card advantage, though its main role is simply a cheap permanent that doesn't cost tempo. Boomerang Basics and The Mind Stone are too slow and don't affect the board against a deck racing to close games quickly, and Braided Net doesn't impact their biggest threats.
