Well, think about what is available.
you can pretty much do without Splata, if you have All Stars in regards to stop ability.
what do you want to focus on?
there are a couple of directions you could go in.
i would suggest using
Miss Ming 1Star
Marcej or Crassus
and Alexie or Loma Noju
that should be 25 stars... but it's hard, since all of Allstars good cards are really high levels.
ofcourse, i personally haven't tried this build, so it's probably terrible
