Failed a long time ago when I deleted my old Diamond save. Didn't know what as a shiny.

Graveler's "teammate" was Magcargo. He paralyzed my Politoed with Body Slam. Next turn, Graveler used Earthquake, KOing is teammate. Then my Politoed used Water Pulse on the Graveler instead of Magcargo, thanks to its speed lowered by Paralysis...

Failed long time ago when a random trainer in Battle Revolution send it out

Failed a long time ago. Didn't care about shiny so traded away

The wild Swadloon used String Shot, lowering my Lucario's Speed. Cheren's Stoutland was send out and used Fire Fang on the Shiny Swadloon before being able to Close Combat him.
