I cant stop for a full rate but i have to say a few things:
Swampy needs roar, brick break does nothing for it.
Bastiodon needs to be scrapped. It has 2 quad weaknesses, one of which to the most common attack in the game (EQ)
Neutral natures are BAD, so switch it on lucario for naiive or hasty. check the pokemon discussion sticky for a good mixcario set
Mixcario fails, it better either fully physical OR fully special.
That blissey is just No. That thing will die to ANYTHING physical. On top of that you are using it too offensivly, its the queen of walls for a reason. go Bold, 252HP/252Def/6SpDef, if you plan on it survivng. And why rest when you can softboiled??? That is seriously beyond me. It doesnt need CM either, its not meant to be setting up. Go standard T-wave/Aromatherapy/Softboiled/Seismic Toss
Alakazam needs modest. Alakazam doesnt need psycho cut. CM variants dont work too well either, it's too fragile. Go choice specs with psychic/EnergyBall/FocusBlast/Shadow Ball
Alakazam wants Timid =/. I prefer Trick Specs aswell.
Now, some things that the person above suggested are wrong, namely:
Bastiodon is bad at the best of times, but attacking with it is laughable. It needs its defences bulked, and it cant attack for the life of it. If you insist on using it, a curse variant of it has been known to work in UU.
Blissey NEEDS HP, but doesnt need SpDef, as its already high enough to support itself. Maxing out its HP and defence are top priority IMO
Ermm, No, max hp makes no difference, if you max it, it makes a 6% difference, Blissey already has overkill Hp, bold nature also makes no difference (119 DEF VS 130 DEF). Whilst calm on the other hand, makes it much more durable, Azelf and Porrygon-z to name a few surpass even ubers at special sweeping, Bold gets 2hko'd by Specs Focus Blast from gengar, which is kinda lol for a sp.wall. That spread "Who is Beelane LOL" posted is one of the best IMO, along with 40 HP / 252 DEF / 216 SP.DEF. <<No sp.sweeper gets past this.
Alakazam doesnt need timid, base 125 is fast enough
No Alakazam still wants timid, you call 339 speed with Modest good ? Timid Always, otherwise you get outrun by stuff you SHOULD be outrunning, such as Gengar. Timid gives you 372, which is significantly better. 125 Speed makes no difference, people still give Weavile Jolly and Zam is no different.
Tyranitar is a bad choice, seeing as almost your entire team gets hurt by sandstorm.
