This is a good example of how to deal with the Zoo matchup as a Goat player. I tend to side in Warriors and additional back-row hate such as Dust Tornado and Seven Tools of the Bandit. I also like to side in Creature Swap depending on the circumstances, since Zoo decks (and Chaos Turbo decks) cannot use Scapegoat tokens to block its effect. Lately I have been experimenting with different side options (and a modified main deck), but I generally like this side deck when starting with a typical Standard Goat list:
I did not play particularly well this series (except for Game 8!). This matchup was more difficult than a Standard Zoo build would be because I had a hard time predicting exactly how many Skills Drains, Trap Dustshoots, and Solemn Judgments I was up against. The best thing to do next time might be to hedge with a single copy of Seven Tools and possibly a 3rd copy of Scapegoat. Skill Drain can be incredibly annoying if you don't see an early Dust Tornado, MST, or Heavy Storm, but adding 2 copies of Seven Tools probably doesn't help fight against it all that much.
