EDIT: It seems probable that the Mood Loser 2 card becomes available with an energy tank of 2K, and Mood Loser 3 with a tank of 3K. In at least one case these cards became available on the next shuffle after hitting each of those tank levels.
OP: I've only been offered - and purchased - the first one. Every game day (and a whole mess of reshuffle cards) now results in three energy upgrades, along with some hell and reshuffles. Am I wasting my time hoping the other two will show up, or am I just having a run of ill luck? My energy tank is 1860.
