That picnic saved me! In the fight with AI Turo, it came down to Brulee (half dead and Paralyzed), Chocopie (almost KO'ed), and Chives (weak to both Iron Valiant's STAB Fairy move and its unexpected Poison move). I could use Play Rough with Chives as Churro was OHKO'ed by said unexpected Poison move. But she couldn't take all that much damage due to others falling to non-Super Effective attacks from other Paradoxes...
And then, as luck would have it, Chives survived on 1 HP. Twice! Back to my Ultra Necrozma victory in USUM. I did Full Restore Brulee after trying to save PP by using U-Turn and it not finishing the beast off, swapping into Chocopie for the sacrifice. But ended up swapping back to Chives as I knew she could outspeed.
Also! Awesome final fight atmospherically. Especially with Tera Blast from Mira. Love my sweet dracocycle!
Gonna catch the last of the Paradoxes next time.
