played Thassa's Oracle in my fourth game of the brawl metagame challenge. In response to the trigger I played Tainted Pact. Since I had 60+ cards remaining in my deck, I let the rope die and it automatically declines every card and sends my deck to zero. Opponent had only red mana and no counterspells in their hand (I checked with duress). Suddenly, in process of declining cards, the game said I lost. I don't know what happened but I surely think I should've won the game.
