Could probably go either way, although I'd perhaps give the nod to Team 2. Partly because Maul is highly familiar with Jar'kai (although I suppose Ventress is a Makashi practitioner, but I digress), and Ventress isn't an expert in Juyo, and because there are scenarios where Dooku will just obliterate her with Lightning. If at any point it becomes a 2v1, Vaderkin is boned. I see that happening more often than not.
