Nice guide. Except, the Heracross on Gretas silver team is holding a Salac Berry, not a Chesto Berry. Oh and BTW, here is another strategy for Pike Queen Lucy's silver team:
Ditto. Yep. Ditto. I used this strategy myself and that's why i won. Use one Pokemon holding a Persim Berry to beat Seviper, have another Pokemon (or the same one), weaken Milotic to around 1/2 health, switch to Ditto. Transform into Milotic, Mirror Coat its next attack and you'll beat it. Then use Surf to beat Shuckle (OHKO).
^Feel free to add it to your guide^
Oh, and you might want to put how much BP for each place. If you do, here is the beginning:
Battle Tower: 1, 2, 3, 4, 5?/15?(if Anabel is beaten), 6?, 7?, ...?
Battle Dome: 1, 1, 2, (?)
Battle Factory: 3, 3, 4/14(if Noland is beaten), 5, (?)
Battle Factory Double: 4, 5, (?)
Battle Tower Multi: 3, 4, 5, 6?, 7?, ...?
Battle Palace: 4, 4, (?)
Battle Pyramid: 5, 5, 6/16(if Brandon is beaten), 7?
Battle Pike: 1, 1, 2, 2, 2, 4, (?)
Battle Arena: 1, 1, 1, (?)
