I heard it's early August. As for Mega Aero + TG Xurk... I'd say some VoltTurn support of some kind, like CB Scizor. Both do appreciate pivoting and imo for Xurk it's required. I'd also say a fast special mon like Latias. Finally, both hazard setting and hazard control (pls don't use defog latias), maybe Nidoking and Starmie, respectively.
