How can i get fast energy in microvolts?

Every microvolts-player want fast energi (also me). But what’s the mode to get energi fast?

I think all microplayers have heard about FFA (Free for all). YukiNagato is the best microvolts player in the world and the words from him is:
“Free For All (More energy but takes longer time per match)
20 kills

or

Team Deathmatch (Less energy but takes shorter time per match)
20 kills

I will device you to play FFA it gives 200-400 or more pr. match!!!

But this is your choice 

If you’re lucky you can find some bug FFA rooms as giving battery every time you kill someone!!!
