By critical losses, I mean losing the entire stack of blue units, considering the fact that the opponent surrenders in a SINGLE ELIMINATION match after the first failure (I don't see the point in participating in a tournament and not fighting after a failure in the first week, especially in a tournament where there is no opportunity to compete in the losers' bracket; you need to win). I imagined the battle not starting on barren land, but with golems, mages, and gargoyles (a ranged unit would be quite logical). In this scenario, even 50-99 gold goblins with morale will win. However, dear PReDS, I mentioned in my message that this is possible.
