Fun fact: I placed First in all 10 of their races.

I was about to win High Spirits, but then someone bought the win (they jumped up from Lap 9 to Lap 16 in about 1 day). After that, I just lost motivation until High Octane.
Ended up buying High Purity using my Earned Gems when it was offered during Thanksgiving.

I didn't start getting up to Lap 15 continuously until Yggdrasil's race, hence why I missed High Resolution and High Score.

Overall, looking forward to hopefully getting High Malicious!

Nice!
I'm also missing 6, but different ones. I didn't start DC until the amuka race so any from earlier were got on the 12th laps. I'm missing fenrir, nucleus, comet, purity, tech and snow. I have all 9 for this third collection so hoping to finish it with malicious to get the big reward!

Only this year I have been good at races.
I have:
High Guardian
High Priest
High Supremacy
High Spirits
High Purity
High Octane
High Superstition
High Resolution
Yggdrasil
High Commander

I think I am doing good.
