Weavile needs to be jolly. A life orb would also work well on it in place of the expert belt, but it's still personal preference.

Energy ball>charge beam on alakazam. Charge beam is a weak attack, and alakazam can't really afford to take a hit, so even though it's good in concept, it isn't the best option. Energy ball is stronger and covers water types like starmie better.

Pain split on dusknoir>protect, as it's great for helping you live longer. Shadow strike is an option over shadow punch as a nasty surprise for azelf and friends. Also, max HP on walls before you even touch the rest of their defenses. Will-o-wisp will burn your opponent, halving their attack, so go careful and put most of your EV's into HP and special defense.

Why in the world do you have attack EV's on cresselia? Again, max out or at least almost max HP on cress, and put the rest of the EV's into the defenses. I also like this set better:

Cresselia@leftovers
Bold (if you can get a good one)
Ice Beam
Rest
Sleep Talk
Charge Beam/Grass Knot

Standard garchomp.

PorygonZ would looks better as a choicer if you're going by an item clause (and it looks like you are. The choice set goes something like this:

PorygonZ@choice scarf/choice specs
MOdest
Tri-attack
Ice Beam
Dark Pulse
Thunderbolt

 

[Laser Shuckle]

you pretty much covered everything except porygon z should have timid if you give him choice specs

Actually, that's personal preference. By going modest, you gain 54 extra special attack (including CSpecs boost). By going timid, you gain the ability to outspeed neutral nature base 90's-base 102's. You can always go modest with a scarf instead, which will also let you pump more into HP.
