Here is my variation of Vintage cube with Storm support. I'm trying to make Storm and Combo as much diverse and fun as possible and sometimes can go for too much support.

Most of the time the cube is drafted with only two players, and we use the Impulse draft method: https://twitter.com/wtwlf123/status/1159617825566126080
The main reason to keep a 540 card size is the Supreme Draft from MTGO we enjoyed.
