I can explain how Warcana pvp work but I have dyslexia so i might explain thing confusing. To win this game you need to get 1st 35,000 kill, even if you see you have more than 4 players you're only opponents is actually on the names on top icon those 2 names is you're only opponents. When summoning units it spawn on you're wave and the 2 of you're opponents. Killing own summon give kill points while killing enemies summon does not give points so summoning units is not useless or making enemy gain faster kill points but its a harrass. You can cast spell on enemies island if possible the 2 names of youre opponents so you can harrass and deny there towers or walls for gaining kill points or hit the resources buildings, careful not to hit enemies waves as killing their wave considered there kills. Players island advanced forward depending how much kill points they have.
