I've tested 4 different lists against Zoo and played a very large number of games. Pre-board I am less than 30%. Is this just an abyssmal matchup?

Even in games when I was able to land Turn 1 chalice, I often still lost.

I have tested propaganda maindeck and it didn't improve my zoo matchup. I even got mad and splashed red for firespout, and only won 3/10.

Does anyone have a list that they claim can beat Zoo pre-board at least 50%, or is that just asking for too much?
