Hello, I'm currently trying my best to lvl as fast as I can to beat a Mecha God

My cost is really low (lvl 55) and my units cost a lot.

Vargas 6

Kafka 6

Zergel 6

Aaron 6

Hadaron 5

Uda 6

Iris 5

Yuuri 6

and a couple of them that are not lvl at all

So my questions are

Where is the best place to lvl up ?

When approximately can I beat a Mecha ?

What Unit becomes my Leader, my Main. For a long time it was Zergel, but Kafka seems awesome and I'm pretty sure a 7* is the best choice for a Leader. Aaron could be a goodchoice too

Thanks
