Just had a painful loss in an edh match

Just got done playing a 4 player match. It was my Greyfax, one player's Ureni, another player's Vial Smasher/Sakshima, and the last player's Liesa. Game admittedly had a slow start, with the Liesa player playing their commander, getting countered, and playing Authority of the Consuls in the same turn.

After that, she resummoned her commander, while I and the Ureni player started popping off. I had token generation and enough untapping my stuff and tapping their stuff to shut 2 people down, and Ureni was getting a ton of dragons.

And then the Liesa player played Bloodthirsty Conquerer and Marauding Blight Priest, their board state ensuring they'd win if anyone either cast a spell or had a creature enter.

Admittedly, we all knew they had some of these laying around, it's just painful to set up so well and then have that player put down 2 cards, swing with a lifelinker, and say "I win."

We were all tapped out, so we couldn't remove her engine pieces.
