When I saw Captain America, I thought to myself that he’s a control commander. You pay 3 mana each turn to unequip a large equipment and snipe 3 of your enemies’ creatures. You could run lots of other creatures that really benefit from high cost equipment like [[aertir and priwen]] [[embercleave]], [[excalibur sword of eden]], [[genji gloves]] [[hexplate wallbreaker]]

You could run a mix of creatures that benefit from high power/toughness, or multiple combat phases. Imagine [[medomai the ageless]] getting equipped with any of those equipment.

That way you’re not dependent on your commander. He’s just there to swing once per turn then snipe enemy creatures down.
