Hello everyone! it's me again! with gen five samples being opened, I figured that I should do a small breakdown on how to build a pretty basic gen 5 balance team! without any future ado let's get Started!
FIRST - Pick your offensive threat/general sweeper! some of the best choices are as follows

for it's High Special attack and great typing! Immune to Toxic spikes and it's Steel/Dragon typing make it neutral to dragon, though it is a bit lacking in it's speed and prefer's to be placed on teams with a lot of support to back it up and threats' like Prank Lando/Faster threats that have good coverage do it also needing Draco Plate + Judgment to do stuff a Stag Mon Like

or

though Gigas is a more common Stag user for it's mixed bulk another amazing choice is

Unlike

passively absorbs Toxic Spikes instead of relying on Rapid Spin to absorb then another good thing about

is it's ghost typing making it Immune to Fakespeed thought Gar does have it's own issues, those include being a Pursuit victim from a Huge Power Mon like

and like Dialga is forced out by prankster nature power

another good choice but is too much of a hassle to really build for is

while it has a good special stat and other thing's it's just to much of a hassle it's a pursuit victim, a fakespeed victim and so much more! I'd just use

or
Secondly - a offensive support IE: Shadow Tag Revenge Killer Mons. Huge Power Revenge Killer Mons Prankster Mon's - this is much simpler as your either going to use

for Huge Power and maybe Stag though it's special bulk is a bit on the low side,

for Stag and Huge power though Stag Gigas is probably better on some teams then others this bit is a bit shorter then the choosing an offensive threat one because there's less choices
Thirdly - Picking your first Wonder Guard... this is gonna be short as hell this bit your first wonder guard should nearly 1000000% Pokestar spirit! as it's the BEST Wonder Guard in B2W2! no questions about it! it's just way to useful and valuable there really is no reason not to use it

(Note Spiritomb sprite is used to represent PSpirit)
Fourth - Picking your second WG/Support WG - This is just gonna be a list

-

and so on each one can do different thing's but each one fill's a different roll as a support wonder guard
Fifth - a Support Mon - This could be

if you didnt pick it for a offensive support mon if you did then a bounce Subpass mon like

or

or a normal bounce mon like

or

work perfectly Fine!
and Lastly - Filler slot - this slot can be No Guard, Scrappy, Imp, Stag if you picked a huge power mon but wanted that support stag provides you can also do another wonder guard slot here if you really want to this filler slot generally is up to you and how you think it helps your team!
Important notes! - Mons like -

-

-

-

Really like having a shed shell! for most sets! if you only slap on the

and not the

On all your support mons Shadow Tag rips it apart! it's also important to note that you need to spread out your coverage moves as Wonder Gaurd's range from many different typing's!

Team Building Though Process (Simple Explanation)
For this im going to breakdown the thought process of the example one balance team
First my choice of a Mold Breaker sweeper was Dialga (

) because of its excellent typing and bring able to be improofed by both the Draco Plate + Judgment Combo And Landorus-Therian (

) do to it having Prankster + Nature power which means the Nature Power will go first, and since Nature Power in Gen 5 when used automatically becomes Earth Quake its super effective against

Rapid spin on Dialga makes Hazard Control Easier to Manage and the Shell Smash + Spore combo makes dealing with opposing mons easier click Spore while behind a sub then set up usually is able to take out two or three mons at least before

could be forced out
Secondly my choice of an offensive support mon was Landorus-Therian do to its ability to pressure out opposing threats like

and

do to them being weak to EQ The Reason I choose Choice Band (

) + Trick is because catching threats of guard like Dialga and crippling there breaking power is very important and in some cases makes it impossible to do if they relied on Judgment to deal damage also with the

it makes damage rolls to

and

much more devastating and pressure the opponent more plus the Support of Prankster Landorus-Therian is just amazing on teams that really like it
My first choice of a Wonder Guard mon was obviously Pokestar Spirit (

) because in any gen before gen 6 fairy types did not exist meaning mons like Pokestar spirit have no weakness meaning either you have to use passive damage like hazards or statuses to damage them or to directly damage them you have to have a dedicated Mold Breaker mon which makes Pokestar spirit reliable into most mons as its forces threats out as alot of them cant hit Pokestar
Next For my second wonder guard of choice is Slaking (

) do to its high attack stat it can work as a offensive wonder guard and a support one with fakespeed since alot of No Guards expect it to be Huge Power and dont often expect wonder guard like that which is beneficial as keeping no guard from being able to sweep is amazing
My Choice of a support mons is Magic Bounce Giratina (

) because of its immunity to fakespeed mons and its high bulk let's it subpass to your sweeper (which in this case is dialga) also if you read correctly you can catch Prankster Spore mons of guard or a no guard mon not behind a sub my choice of Item for

is its Griseous Orb (

) because it cant be tricked stopping trick scarf mons like Wonder Guard Deoxys Speed
And Lasty my filler mon of choice is imposter Blissey (

) with The Draco Plate because of how common

plus Judgment is letting you pick up at least one KO with your Imposter mon and if your opponent doesnt play careful enough you can subpass to your Imposter Blissey and if they clicked a set up move usually shell smash on Dialga and Tail glow on Gengar you can pick up possibly three KO's if played right!
