Ethernaut Candy without spending max particles.

I got a quest to unlock a max move for 100 ethernauts candy.
At first I was disappointed about spending particles in this very important weekend. But after gathering three of the quests I unblock a movement in my zacian and it counted. So I plan to do this with my zacian and zamacenta.
Also, I'm thinking that if I run out of their candies I'll invest my rare candies on them and it's technically a 220 earning of ethernauts candy, plus I invest on the movements.
