Triple triad is extremely confusing to me. Some of the NPC's won't even battle me so I can't get the cards to farm some imperial guy or something. I'm so lost! I have no idea what I'm doing. All these guides say to farm some imperial guy with a specific deck but I went around trying to get these cards and none of these npc's will battle me for a chance to win their card or something? 

Gosh this makes no sense...
