Flux - a potential in tournaments?

I'm seeing a very big potential of Flux in Tournaments. There are a lot of heroes that could prove a good synergy with his ulti. Some examples that I can think of:

Flux + Kraken + Bombardier

Flux + Plague Rider

Flux + Tempest

Flux + Pyromancer + Pebbles

Flux + Engineer

Flux + Bubbles + Hellbringer

There are a lot of options. What do you guys think?
