Featuring yours truly.
I ran a Separatist list with 5 vulture-droids (3 with shells, 1 with buzz swarm and 1 empty) with a quasi-minimalist Maul with Grievous and Hate.
My matchups leading to this game were:
R1: Resistance 2 T-70 with 2 RZ-2
R2: Double Firespray list with Emon and Boba
R3: 3 VetGunner Y-Wings with Ion, U-Wing with Leia
R4: 5 Y-Wings with VetGunner and Ion (one w/o Vetgun)
Top 4: Drea + 3 Lok Revenants with VetGunner
and the final game had me facing an all-around solid Rebel list with Wedge, Thane, Braylen and a Leia Partisan U-Wing
