I usually play with a deck that has 20-21 lands. For some months now, flooding in one or both games of a Bo3 match has become very common. That is, in the first twenty cards, at least ten lands are drawn—something that can certainly happen, but not with this frequency in reality. About half of the matches go this way, to be precise, 49.67%. I have kept a statistical record of it.

There is therefore a serious issue with Arena's shuffler, and it is more necessary than ever to address it, because this situation causes frustration, worsens the gaming experience, and drives new players away.
