With the 2X Enel team, going with Gaimon until I can get Aokiji's special ready. I don't have a Zoan Lucci, so I'm using miss Valentine. But I go
Gaimon special
Valentine special
Doflamingo special, to get the blues on Enels
Aokiji special
then gaimon>enel>enel>whoever to end it, and it's not getting anywhere near that. My enel is only 50, but I was using a max with it, and the other levels shouldn't matter afaik
I also tried G3x2 with Int Mihawk and 3 penguins, but that gets me to 2 million because of bad orb luck. But I think that's how I am going to have to go.
