My most brutal loss was from my first month, when I was really trying to perfect my inexpensive line ups and was one win away from bronze 1. The match was a 99 mana ruleset. I spent my entire clock laboring over every choice to make the perfect water magic deck, and I thought I had an auto win because my oppenent only played one card. However, it was Torhilo (magic resist) and Bortus the summoner (magic reduction). My full line up of magic creatures did exactly zero damage and Torhilo chortled his way to a flawless victory over my squad.
