Whenever Théoden or another Human you control enters, target creature gains double strike until end of turn.
Flood the board with Humans, using each one's entry to grant double strike to a beater (often a wide-attacking token swarm or a single Voltron threat) and crash in for lethal red-white aggression. You curve out cheap Humans early, then chain enters-the-battlefield triggers to repeatedly double damage output. The deck closes games fast through combat before slower decks set up.
Cheap 3-mana commander that immediately enables aggressive starts
Double strike turns mediocre attackers into game-enders, especially with trample or anthems
Deep, well-supported Human tribal pool in Boros colors
Token-makers create many ETB triggers, stacking double strike repeatedly
Boros lacks card draw and ramp, leading to running out of gas
Heavily reliant on combat damage—vulnerable to board wipes and fog
Double strike on a single attacker is fragile to spot removal/blockers
Two-color identity means no easy access to recursion or interaction tutors
Snowballs your board as each Human ETB pumps the whole team alongside double strike triggers.
Add card-advantage engines that fit Boros aggression—Skullclamp, Reconnaissance, and impulse draw like Outpost Siege—to refuel after wipes. Tighten the curve with efficient Humans and token producers (Captain of the Watch, Brimaz), and include protection like Heroic Intervention, Boros Charm, and Flawless Maneuver to survive board wipes. Top-end finishers such as Embercleave, Coordinated Charge, and Craterhoof-style overrun effects (or red equivalents) convert double strike into one-turn kills.
