Boros Dwarves goes wide with cheap aggressive creatures like Dwarven Mauler and Warden of the Inner Sky, then buffs them heavily with Equipment like Leyline Axe and Lavaspur Boots. Strategic Betrayal pressures their board by forcing them to exile one of their own creatures while also stripping their graveyard, removing a threat and denying any recursion value. Get Lost is flexible removal that cleanly answers their creatures and any planeswalkers they might bring in post-board. Requiting Hex is still fine early against their 1-2 mana creatures, but we trim one copy plus Erode for more proactive answers to their bigger midgame bodies like Thorin, Mountain-king.
