How To Play Onward

About Onward, from BoardGameGeek:

Onward is the spiritual successor to Skytear, the competitive card-driven game inspired by MOBA video games such as League of Legends or DOTA2. Players split into two teams, with each player controlling two or more champions. The goal of the game is to destroy the enemy nexus that is a portal in the enemy base. The game takes 45 to 90 minutes depending on the map that can have two or three lanes. Lanes are corridors connecting the two nexuses and are populated with towers and minions from both teams. Towers are defense structures preventing enemy champions and minions from rushing into the nexus. Minions are weak units that grow in strength as they increase in number. They always try to advance toward the enemy nexus and attack any enemy in their way. Jungles are dangerous areas between lanes where champions can venture to defeat monsters to gain gold and buy powerful items. The river is a central area where your champions can go fight the colossal outsider... or die trying! -description from the publisher
