We haven't measured this pack yet
We've sampled 1 pullfrom this pack so far — too few to publish a return that wouldn't just be noise. The feed is sampled every 2 minutes, so this fills in on its own. Until then, everything below is Monster's own published odds.
We publish a measured return once a pack reaches 10 attributed pulls, and rank on it at 100.
