I will use @FairlyRandom to get our results. 1 = Heads, 2 = Tails. Market resolves YES for heads, NO for tails.

If you bet and comment, I'll send you 10 mana. Only for the first three. Api trades don't count.

If the market has closed and I haven't prompted fairly random yet and you do so, I'll give you 20 mana.
