I might have actually been in the first round...
Anyways, this is what I missed (followed loosely for a while after I unofficially quit:)
2/14/2013: Fake Out unbroken, CC bonus for maxed mons changed to scaling system, and no more stealing Rotom appliances from arenas.
2/10/2013: Project Moderators have been given the power to revoke counters from staged "Crush the Combee"-style matches. This will probably only affect 1% of matches, though.
2/7/2013: Arena Trap and Baton Pass now have their in-game effects (as an option for the latter).
1/18/2013: Huge Power & Pure Power hot-fix.
1/17/2013: Forewarn's effect changed to a much less haxy one, UC payouts for DQ battles have received a hotfix.
1/16/2013: Mass Trait overhaul, Part 2: Levitate is now Innate, Pokemon that got Levitate due to anime precedence no longer get the Levitate ability but get the Levitate command instead.
12/29/2012: Leech Seed consistent, Reflect & Light Screen more powerful vs. combos, & Mass Trait overhaul, Part 1.
12/23/2012: Embirch and Flarelm have been updated based on CAP threads, Rock Smash has been buffed. | Agility (Evade) & Teleport (Evade) no longer have evasive properties when combined with a suitable damaging move.
12/17/2012: Rank 0 Bonus has been abolished, & Wonder Guard has been buffed, as per ASB Council Votes.
11/26/2012: Dodge Combos are dead & have no saviour. Also, Damaging Priority Move Substitution Class implemented. | Illuminate no longer broken.
11/12/2012 Magic Coat Audit.
I just realized that there may have been a massive error at veekun regarding a mix-up of Magic Coat and Role Play users.
As a result, there may be a significant number of Pokemon using Magic Coat that actually learn Role Play.
Due to the competitive implications of this, please audit your Pokemon. If you find out they do not actually have Magic Coat, please make a prize claim thread post indicating you are swapping out an illegal Magic Coat for another legal move (if it was a starter Tutor move on a No Egg Move Pokemon, you must select another tutor).
This audit will apply to all new battles. If you currently have an illegal Magic Coat Pokemon in a battle, you may continue to use it until the end of the battle.
11/10/2012: Anime Only and Manga Only Attacks have been implemented. Anime Only and Manga Only Moves Cost 3 MC to purchase.
09/24/2012: Itempalooza breaks ASB. News at 10.
09/22/2012: Syclar revamped as per this thread.
08/11/2012: Changed Focus Energy and added Evolutionary Stones as hold items. Made Plus, Minus, and Stench Traits. Gave Volbeat and Illumise Innate Levitate.
Any summary of these? I'm annoyed that Abomasnow lacks Magic Coat now (grrr...) but meh.
