How it works

After this market closes, I will ask @FairlyRandom to generate a random number M among 1 to 100 in the comments. The Mth unique trader of this market wins 300 mana from the lottery prize pool, if such a trader exists. Otherwise, the lottery falls through till next time.

For free play, make a trade with 1 mana and sell it. Your trade will be recorded and you will become a unique trader.

This market will resolve to xx%. The first balloon-borne astronomical telescope, Stratoscope I, featured a primary mirror with a diameter of about xx cm.
