I'm currently at level 57. My main strategy right now is to start each morning doing a 100% power mission. I'm currently doing the Local Mini Tour Support on the local gig circuit. That takes about 5 hours.

After that I use up my remaining missions either doing lower power missions in Home Town or take music lessons to increase my skill level.

I hope for pizza while doing these smaller missions and lessons.

Once my power is drained down to a few percent, I use Pizza or let myself charge up till 100% again. I then do a last mission for the night, and find myself charged up in the morning where I wash, rinse, and repeat.

I did purchase one of the 12 pack special offers for 100,000 starbits also.

Here's a screenshot of where I'm at right now.

I was curious, are there any benefits to using certain cards. Like right now I'm using the Classic Punk card and I think a Microphone. Does this affect my rewards in anyway, or change the play of the game somehow? Would I be better using something else?

I was using the default Busker up till last week when I realized I could change the cards.
