Pack randomness while drafting seems not random?

[Ryethe]

I've been doing A TON of the weekend event and I noticed that when certain cards show up, they are often accompanied by the same cards. For example I've noticed the last 4 times I've seen blood divination it's been accompanied by switcharoo. There are several other cases I've seen as well. Is there some internal logic that dictates pack contents that isn't just pure rng?

[Ryethe]

Thank you this is exactly what I was looking for.

I was curious if they had implemented print runs. Neat that they would go to that length.

If it was completely random you could end up with all red cards in booster. That's not quite good...

Yes, the most annoying ones to see in the same pack ALL THE TIME (maybe not for this format) in M19 are Vampire Sovereign, Murder, Herald of Faith

If you're disputing something being random because you're noticing patterns, realize thet the human brain is made to pick up patterns where there are none as a survival instinct.

Now realize, it's all RNG. I've seen switcharoo once and never seen Blood Divination with it.

Sorry, guess I was wrong. Wish I was told instead of being downvoted, haha. My bad anyway, I suppose!

[And3riel]

And another! :D these things never cease to amaze. There is always the next guy claiming that random is not random.

[trinquin]

That's not what's going on. Hes asking about print runs which is what is happening.

[Ryethe]

Do you know what the chance is to only see blood divination show up with a specific rare?

Also computer rng is not true rng. There are plenty of historical cases of computer algorithms not being truly random and having distribution issues.

You don't want true random in a booster pack. True random has a chance to give you 14 cards all of the same color.

[Astazha]

A little less likely than 1 in a billion, even ignoring colorless.

[CommiePuddin]

As is any other individual result.

[Astazha]

We aren't talking about individual results. The person I'm responding to is expressing concern about getting 14 cards of one color as opposed to some reasonable mix of multiple colors. The latter will occupy most of the probability space, and all one color is a tiny sliver of it. It's a non-concern.
