Ok. Just so you're aware I think the people that have a BCC Scyther used an Adamant Mew w/ Sweet Scent. That is possible to get through the Rage glitch (double battle, transform into a pokemon with Rage + 3 other moves you want, use Rage until the "rage is building" message shows up, then finish the battle w/o switching it out or having it faint. That way one could have access to both a sync and sweet scent.
Also, try looking through people's threads for a BCC Scyther to see what spread they got so you can duplicate that.
Uh... what's the rarity of Scyther in the BCC? If it's 5% or less it would be in one of the slot 1 spreads somewhere... It would still be hard to find but you're limited to 5 different slots instead of all 12. Assuming they were correct that is. I honestly have no clue.
Hey I saw you talking about the BCC encounter slots. From what I picked up in the IRC I hear that the encounter slots are actually picked backwards. Encounter slots are picked based on a percentage thing (0-99). Normally the slots 1-12 are picked by the numbers 0-19, 20-39, 40-49, 50-59, 60-69, 70-79, 80-84, 85-89, 90-93, 94-97, 98, and 99 starting from slot 1 (meaning slot 1 is 0-19). However in the BCC they're reversed apparently. So slot 1 is 99-80, then 79-60, etc.
That's what I've heard. So if you're after something that's rare try searching for spreads that are normally in slot 1.
That's great to know! You know how hard it was to capture cresselia and Mesprit since the only way I knew to switch my frames from even to odd and vice verse was by walking 128 steps? This is great news!
