It seems like the key player right now is Pica. As long as he is active, no one can get close to Doflamingo since he could just eject them from the castle again. It really comes down to Zoro and Kin'emon since they are the only ones left in the castle. I'm guessing they will fight Pica so Luffy can focus on Doflamingo.
