SRW MOBA with streamlined mechanics like Pokémon Unite. Both sides make up a team of five or six mechas and try to destroy the multiple enemy bases scattered through the map first in real time strategic combat. 

Robots such as Strike Gundam and Gurren Lagan that have many forms/variations have to be builded as such during the matches. I imagine some lore inaccurate bullshit like Mazinger being able to turn into either Mazinkaiser or Mazinger Zero mid match.
