With five Strength, five Willpower, +2 Resist, and Shift five, this is a card that turns up early, hits hard , and is ridiculously hard to get rid of
Imagine it dropping in something big like Muxus, Goblin Grandee for free on turn 2
Playing Mishra's Factory in something like RDW might cost your good and average draws a small fraction of a % (total stab in the dark but we will call it 0.2%) in exchange for a slight improvement to your weaker draws
Shortly after while telling someone about this deal we realize how dumb it was and feel bad that we could have gotten probably twenty times the amount of cards for that land
The idea was that since people might only spend $20 to $40 on cards and those cards would be randomized, you could sit down to play a game with someone who had cards that you had never seen beforepossibly never even heard of
