Playtesting might be malfunctioning

I was playtesting a deck which had Dark Ritual as a 4-of, the chances of it being in my opening hand were roughly 40 %.

In spite of that, in more than 20 playtests I failed to see it in my opening hand. I -did- draw into it on following draws, but it still seems like it would be too much of a coincidence to miss a 40% chance in all of 20 games.

Has anyone experienced anything similar?

The problem wasn't existing by sampling 10 opening hands using the "Draw hand" function.

The thing is, it's not like it has a 40% chance by itself. It has a 40% chance, but so might 20 other cards or so. So you have to keep that in mind. Not sure how to describe that very clearly, sorry.

No, Dallie's correct. He has a ~40% chance of drawing at least one Dark Ritual in his opening hand. That means he has a ~60% chance not to draw it. Since each game should be independent, that means he has a .620 chance of not drawing it in 20 games, which is less than 1%. Possible, but highly unlikely.

  • .6 exp(20), not .620

I stand corrected then. I forgot about the 20 games part.

Image is now showing correctly and I have succesfully had a Dark Ritual in my opener for playtests today.

Maybe the missing image that needed to be updated had something to do with it.
