Had an annoying experience fighting the lvl 20 npc when this situation came into effect. He used his "subtract MAX HP from all cards on the field" unit skill, this killed all 4 of my units and 2 of his lvl 7 Earth Dragons. He had 1 LP left and I had 2 LP and was able to revive 2 of my cards. I thought i was okay seeing as he had 1 LP, because surely 1 of his cards would be removed before both of mine. But no, my 2 level 3 cards were removed first thus losing me the game.
I'm thinking it's because my units were placed many rounds ago, and his dragons were relatively new on the field. Still really annoying though!
