This team in Season 03 is entirely unchanged from the previous team. As I said earlier, the only difference this season was that Zygarde was an optin in the roster. I decided that this team worked well in the previous season and already heavily countered Zygarde, so there wasn't a point in changing it. Right?
The team did not do as well this season, but it still overall performed really well. I'm not a big fan of how many ties I had this season, but a win's a win nonetheless. The bigger issue with this season came down to how well I prepared for the season.
If you scroll down, you'll notice that there are two separate entries for my run, one starting at Rank Z and one starting at Rank F. I refer to these two eras as BME and ME: "Before Mewtwo Era" and "Mewtwo Era." The Mystery Gift that added Mewtwo to the roster took place in the middle of the season, and I did not prepare for this when deciding on which team to play. I didn't want to change the team mid-season because of this, and my score went down overall, but I wouldn't say I'm disappointed with the end result. Regardless, Mewtwo was the biggest threat against this team.
If I had one more first place run at any point, I would have hit Rank A with one fewer games and won with an overall win rate in the 70%s, so it's not like it was a disaster.
