How To Play Krieg Eterna

About Krieg Eterna, from BoardGameGeek:

A game of Krieg Eterna is divided into three separate rounds of play, where your objective is to win more rounds than your opponent. Each player's side of the field is split into three rows: melee, ranged, and siege. At the end of each round, the player with the most total strength across all of their rows wins that round. Players take turns playing cards until all players say "pass", after which they score the field, discard all cards on the field to the graveyard, and then start the next round. -description from the publisher
