Curious.....I do at home drafts with my nephews and brother. Tonight there was just three of us. We're drafting Gatecrash, long story short what is the possibility that someone drafts three {boros elite}. There are only nine packs.
I normally wouldn't question this but were playing with the prize to the winner is a rare of choice from each losing players draft and I got a {Boros Reckoner}.
It's uncommon. Out of 27 uncommons, the odds are against getting 3 but its not impossible.
It happens. Did a 3-person draft with a couple friends recently and we had 3 {Elusive Krasis} going around the table.
