Kambi has 0 strength in Close Combat, but it carries Summon Avenger. When it’s removed from the battlefield, it summons Hemdall, an 11-strength Hero. A cheap card that leaves a much bigger one behind is a neat trick. Hemdall is a summoned token, so you can’t collect him as a card of his own.
You win it from the armorer at the Beauclair Armory in Beauclair during Gwent: Never Fear, Skellige’s Here. Only one copy exists.
The Skellige deck has its own perk as well: at the start of round three, 2 random units from your discard pile return to the battlefield.
