lol. finished the game. i gave up on getting one gold medal during the 3rd chapter. came back to it after beating the harder levels and aced it first try.
easiest way is to use "Parting Gift" and "Peasent"...just get parting gift into play and keep sending peasents out. when the opponent kills the peasents it hurts their portal. i beat them all. the only offensive card in my deack was peasents (14). I had 3 parting gifts and the rare card "Kamikaze" which is just parting gift but 2 damage.
this game is so easy, but boring. all u need to do is but the horses upgrade and they go over and steal the flag and bring it back. all u need to do is cover them for like 2 waves and u win. i dont understand y people say it is hard and u need to trigger waves.
a hint...try to balance the big ones for as long as u can to rack up some extra time. u can just try to get them to sit in the middle and keep it up for as long as u can to gain extra time
