Commander’s Horn is a special card that doubles the strength of all non-hero units in the row you choose. Only one horn can be active per row, so pick the row with the most units.
Three copies exist, and you buy them from innkeeps and merchants. One comes from the innkeep at the Inn at the Crossroads in Velen, one from Marquise Serenity at the Passiflora in Novigrad, and one from Stjepan at The Alchemy in Oxenfurt.
It works in any deck, and it’s especially strong on a row full of Tight Bond units.
