Hi! I think voting is a really good way to get Mana. It doesn’t seem like a lot at first, but it builds up really quickly (especially since it’s double rewards week) and only takes a couple minutes.
Champ maps too, especially haunted manor. These can be a lil intimidating, but once you reach skilled (if you aren’t already) they’re SO worth it. First time I did it, it took me hours lol but now I’m getting it in like 20-30 minutes. (This still isn’t fantastic but it’s a massive improvement haha)
If you practice and keep an eye out for bits of advice, they can cut your time in half.
I know people record their speed runs (like 8 minutes it’s insane) and upload to youtube, so they’re worth checking out.
Hope this helped out a bit.
