What is the most FUN build for you this season?

It doesn't have to be the OP 1-click room-clear, really just any playstyle and or build that captivated you.

I tried minion master for the first time, and it really didn't click with me, although command skills made it more interactive than I initially anticipated. I think the most fun for me remains the mid to early lategame invoker, it's a bit too much button pressing to be a meta top pick, but at least I'm not bored out of my mind when grinding maps.
