Or you could use more regular balls... A Dusk Ball at night with Capture Power level 3 active works very reliably at catching a paralyzed/asleep Virizion with 1 HP remaining, for example. (and looks nice, too) I'd highly recommend looking at Buckert's Soft Resetting guide over in Orange Islands to help make things easier to SR all these legendary Pokemon. (and remember to NOT screw with the 3DS clock or else you'll be locked out of time-sensitive events for 24 hours from when you messed with the clock)I actually need a few more when i try SR for the dogs, musketeers, and any other VGC legal Legendary
