Major swampert weak.

After hera dies it pretty much says gg.

 

[Hypnosis]

Should I do: Sceptile > Alakazam, because of the swamp weak and because I have a total of 3 psychic types?

 

[chaos952]

Major enemy Heracross weakness also. Metagross and Heracross are 2HKOed by CBcross' Megahorn, so that's good effing game for you.

 

[Hypnosis]

What do you think I should change then?

That's pretty good. I do personally hate fire blast and I would replace it with Flamethrower, but this looks good.

Heracross (M) @ Choice Band
Trait: Guts
EVs: 12 HP / 136 Atk / 108 Def / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Brick Break
- Focus Punch/Earthquake
- Megahorn
- Rock Slide
A better set for Heracross (IMO) would be this one:
Heracross@Salac berry
Trait: Swarm
EVs: 252 Atk / 252 Speed / 6 HP
Adamant Nature (+Atk, -SAtk)
- Reversal
- Endure
- Megahorn
- Counter/Rock Slide/HP Rock/ Rock Tomb
You probably know the Endure-Salac berry-Reversal combo, so i'll skip that. Endure also helps Megahorn with Swarm, useful if you're facing something Reversal's weak to. The last one could be Counter (just because...ya no), or a Rock move. Rock Tomb can be used on fast Pokemon to ensure a quick Reversal without getting Ko'd, but you sacrifice power and accuracy.

Blissey (F) @ Leftovers
Trait: Natural Cure
EVs: 212 HP / 252 Def / 46 SDef
Bold Nature (+Def, -Atk)
- Aromatherapy
- Seismic Toss
- Softboiled
- Ice beam/Toxic
Thunder Wave on Blissey is just annoying. Replace it with Toxic which is more practical, or the standard ice beam.

Starmie @ Leftovers
Trait: Natural Cure
EVs: 42 HP / 216 Spd / 252 SAtk
Modest Nature (+SAtk, -Atk)
- Ice Beam
- Rapid Spin
- Recover
- Surf
I personally use thunderbolt instead of spin. Doesn't mean it's bad though, to counter Skarm/Forretress.

Metagross @ Leftovers
Trait: Clear Body
EVs: 78 HP / 252 Atk / 92 Def / 88 Spd
Adamant Nature (+Atk, -SAtk)
- Agility
- Earthquake
- Explosion

Good...

Alakazam (M) @ Leftovers
Trait: Synchronize
EVs: 6 HP / 252 Spd / 252 SAtk

Yep

And that's it. Hope I helped.
