Test this precon
Before you buy it: goldfish an opening hand, or simulate thousands of games to see how consistently Ob Nixilis of the Black Oath comes down on curve. Nothing is saved.
Ob Nixilis of the Black Oath stays in the command zone — this goldfishes the other 99 cards. Draw an opening seven, mulligan with the London rule, and step turns to see how the deck plays out.
