Is the giveaway still going on? I would like the Latias, Latios, and a modest Jirachi (no nickname please)
Here's a competitive strategy. Use a shuckle as a staller. Have the shuckle hold the item Leftovers. Use substitute on your first turn, then use toxic, after use knock off (egg move) to take down your foe's item. Keep using substitute when your old one fades away. If your running low on HP, use rest to regain HP.
