What would be my best team for the characters that I have

I'm a returning player after a 4 month break, level 73. I am wondering who I should start to farm and use in an Arena team that can get me to the top 100. Here are my following characters:
Luminara
Mace Windu
IG-86
QGJ
JC
GS
Ig88
Count Dooku
Darth Vader
RG
Plo Koon
Ahsoka Tano
Lando
Greedo
Tie Fighter Pilot
Yoda
Rey
Bistan

You could do a mostly Jedi team with QGJ, Rey, Lumi , Ahsoka, and RG - but it is not what is typically seen in top 100. Rebels work well, characters that dispel are a must for top teams unless you do massive damage. Top teams that don't have tournament characters or EP typically have excellent synergy (e.g. rebels, top jedi, strong empire team) or have an annoying combination of taunts, stuns, and massive damage.
