Anything else we kind of want to talk about with win rate and how it might be hard to understand or there's more factors than people are aware of?

Alex LienGUEST
So one factor, this is going to be probably like a pretty recurring theme for like a lot of data stuff is selection bias.

Alex LienGUEST
So what selection bias means is like there's the data that you're not seeing by just looking at win rate or just data in general, which is like the player's agency, basically.

Alex LienGUEST
So for example, like the person who decides to play Arkham Daxon or the person who decides to play Sissy, like their personal like selection on like why they choose to play which deck.

Alex LienGUEST
So if you have a deck that like only good players, exclusively good players choose to play this deck, then like the win rate on that deck would naturally be like very high because it's like that's what all the good players play.

Alex LienGUEST
So you generally see for like, I think you were seeing this for the Arkham before where like, Notorious was the only one winning with it for like a while.
