Boros Dwarves curves out with cheap creatures and Equipment like Leyline Axe and Lavaspur Boots, so a second Pinnacle Starcage exiles Dwarven Mauler and other cheap creatures and equipment outright. Rest in Peace has limited upside since they aren't graveyard-reliant, but it costs little to include as incidental disruption; prioritize it less if you need the slots elsewhere. Trim slow reactive spells like Three Steps Ahead and Jace's Machinations since you need to stabilize against their fast curve rather than grind. Lean on Day of Judgment and Get Lost as your primary sweeper/removal against their aggressive equipment-based threats.
