While playing “color mastery” in the event list with the starter decks, I'm currently stuck against the ai opponent. It happens repeatedly when playing the white (Plains) colored starter deck against the green (forest). The 4th AI opponent. It occurs just after turn 6 I believe. I'll pacify the gigantasaurus, attack and pass, the opponent plays a 5/3 hexproof creature and passes, I attack and kill the 5/3 hexproof in combat and pass. The ai opponent goes into second main phase after playing a forest and then nothing happens. I can't concede the game, and the opponent never leaves the 2nd main phase or plays anything else. Upon my 4th attempt at reboot Ajani Goldmane - keep the peace starter deck vs ai opponent #4 or IV Vivien green Forest deck, I was able to get the opponent to play his card and pass the turn back
