tips on farming iso?

So, I'm relatively new. I have a few 5* and 6* I want to rank up, but the problem isn't the catalysts, it's the isos. Help please?

Yeah, I'm in a small alliance. They're kind of really inactive, so it doesn't help. Arenas get so tiring after a while, because I'll have a 10-15 win streak, and then have to start all over again.
