Haste (This creature can attack as soon as it comes under your control.)
Whenever Eivor attacks, it deals damage equal to the number of Equipment you control to each opponent.
Eivor is a RW equipment-aggro commander that turns your suite of attached gear into a Pinger. Flood the board with cheap Equipment, attack with Eivor's vigilance and haste for repeatable direct damage to every opponent, and back it up with combat beats. You win by stacking Equipment count high and connecting in combat while the attack trigger chips life totals away.
Built-in haste and vigilance means immediate, low-risk attacks every turn
Damage hits each opponent simultaneously, scaling well in multiplayer
Equipment density also makes Eivor a fast Voltron threat
Boros has deep, cheap equipment and equipment-matters support
Relies on Eivor sticking; heavy commander tax after repeated removal
Equipment-heavy hands can be slow without payoffs on board
No card advantage engine in the color identity beyond equipment cantrips
Vulnerable to board wipes and artifact destruction stripping your gear
A cheap living-weapon Equipment that also scales the rest of your artifact count.
Add free or cost-reducing equip enablers (Puresteel Paladin, Sigarda's Aid, Brass Squire, Bruenor) so you can deploy more Equipment per turn and maximize the trigger. Lean into extra-combat effects like Aggravated Assault and Combat Celebrant, plus protection like Swiftfoot Boots and Lightning Greaves, to make Eivor connect every turn. Tighten the curve with cheap, value-dense Equipment and add Open the Armory/Steelshaper's Gift tutors to assemble your best gear consistently.
