(If you want to battle me i'll be ready sometime within the next month)

For starters, in tiered macthes which are most battles you'll have here, speed boost Blazekin is banned. So you could replace him with Infernape running:
Naive @ life orb
4sp atk/252atk/252spe
- Overheat
- Close Combat
- U-turn
- Stone Edge
This set is great set to use especially in conjunction with Foretress and volt switch of course Infernape isn't to bulky but should be able to make a few switch ins and keep momentum up for you.
Another huge problem is the lack of a dedicated wall, foresters should never run 252Spe ever! So if I suggest
Relaxed @ leftovers
252hp/252sp def/4def
Keep the moveset the same, I prefer to have a specially bulky Forretress cause he already takes hits pretty well even without to much def investment. But you could alternatively add more to def than Sp def if that's what you wanted to do.

I love Heracross, too bad he doesn't stand a chance in most cases due to his speed. You should run an adamant Heracross and slap a choice scarf on that bad boy!

For starters, never, ever, ever use Speed EVs on Forretress; it's pathetically slow, even with full investment. A Relaxed nature with 252 HP/176 Def/80 SDef or a Sassy nature with 252 HP/4 Def/252 SDef are also the preferred spreads; choose which nature/spread suits your fancy.

Samurott is outclassed by loads of stuff in OU, particularly Gyarados:
-Dragon Dance
-Waterfall
-Stone Edge
-Earthquake/Bounce
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Life Orb/Expert Belt/Wacan Berry/Lum Berry

or
-Substitute
-Dragon Dance
-Waterfall
-Bounce/Stone Edge
Nature: Adamant
EVs: 56 HP/248 Atk/204 Spe
Item: Leftovers

or
-Dragon Dance
-Taunt
-Waterfall
-Stone Edge
Nature: Adamant
EVs: 176 HP/128 Atk/204 Spe
Item: Leftovers
Ability: Intimidate

or
-Rest
-Sleep Talk
-Waterfall
-Dragon Tail/Roar
Nature: Impish
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Intimidate

or
-Waterfall
-Dragon Tail
-Taunt
-Thunder Wave
Nature: Impish
EVs: 248 HP/252 Def/8 Spe
Item: Leftovers
Ability: Intimidate

If you want to keep Samurott, a specially-based mixed set is ideal. Dig is terrible competitively; it's way too easy to get around:
-Hydro Pump/Surf
-Ice Beam
-Hidden Power (Grass)/Grass Knot
-Megahorn/Superpower
Nature: Naive
EVs: 4 Atk/252 SAtk/252 Spe
Item: Life Orb

Samurott can also pull off Swords Dance quite nicely because it has Megahorn to hit Grass Pokemon hard; Water + Bug have good coverage as well:
-Swords Dance
-Waterfall
-Aqua Jet
-Megahorn
Nature: Adamant/Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Leftovers

Smeargle doesn't really need Substitute because whatever was put to sleep by Spore can be used as set-up bait for Shell Smash + Baton Pass. A way to help ensure the pass is more useful than Sub, such as Magic Coat (to reflect status back at the opponent) or Taunt (to prevent setting up altogether). To optimize bulk, this spread is used: 80 HP/96 Def/80 SDef/252 Spe.

Torterra isn't a good Pokemon to use in OU, honestly. Normally, I'd add in Ferrothorn to replace it, but it shares a 4x weakness with Forretress. Forretress can already handle the entry hazard laying, so why not give Breloom or Virizion a shot? Breloom hits harder than Torterra can, while Virizion is faster (Breloom is also faster than Torterra, technically):

Heracross is really better off with max Attack and max Speed; I don't see what purpose your current EV spread serves; it looks random to me. Also, give it Flame Orb or Toxic Orb to readily activate Guts.

For the most part I agree with platinum dude, I was thinking the same with adding Breloom and trashing Samurott. Really what you could use is another wall to sponge attacks, you could use the physically bulky Forretress in conjunction with a

Jellicent
Bold @ leftovers
248HP/216Def/16Spe
-scald
-recover
-Taunt
-will O wisp/toxic

This is one of my favorite pokemon to use competitively this gen, he is just so versatile, access to a fast taunt to stop slower Pokemon from setting up and access to recover is amazing. He is also handy for blocking spinners from removing hazards on your side of the field. Samurott is good but doesn't compare to the beast that is Jellicent.

If you can find a good balance with the above changes you have the potential for a solid team. Happy team building! Also I'll be around to help with the aquisition of Pokemon of you need it. Just PM me.

@platinumdude and @windowx I was worried about blaziken thanks for the advice. I will be ditching sammurot and torterra then replacing them with jellicent and Virizion. Il'll try to elaborate more when i get back
