One unit takes the field. Drag each challenger into how well it beats it, cost for cost. Hard counter crushes it, soft counter has the edge, avoid loses the trade.
The challengers
Sort them
Verdicts come from a cost-for-cost, stand-and-fight model (blacksmith-equal, no micro, no pathing): how efficiently equal resources of each challenger trade against the featured unit. Bonus damage and armour matter; kiting and terrain don't. Treat it as a tavern argument settler.
