Tips for a Returning player

TrueBlueBlazers

So after about two years, I'm back to playing the game. The last time I played, it was still the Ant-Man event and ever since then, I've missed out on a lot. In terms of my progression, I still don't have a 4* though I have about 20 3* champs.

I didn't know about beginner arena tiers so I wasn't able to progress and get 3* and 4* champs that way so I was wondering how I can make up for it now and get these better champions besides completing Act 3 & 4. Any tips?
