The likely range for its true win rate is 41.1–59.8%, so it is too close to call against a coin flip. It appears in 11.3% of the 948 TvP games in the guide sample. This guide is newly published, so there is no weekly trend yet. This is still a small sample (n = 107), so treat it as a directional read.
