I was playing an EOE Traditional Draft, match 1. It was game 3, and I had attacked with a Comet Crawler, unbuffed from the sac buff. It had the Requiem Monolith active ability on the creature and a Dark Endurance buff active. The opponent triple blocked with 1/1s. After damage was dealt, a big ol DEFEAT appeared on my screen and it kicked me out to the menu.

I tried thinking of a way this could have potentially decked myself but I just don't see it.
