lol actually thunderpunch is great on a metagross...as you said...thunderpunch takes care of bulky water pokemon and it does 150 damage to super effective...while facade only does 140 and everyrthing else you really dont need to worry about because meteor mash and EQ are there...but if they are cut in half, then well metagross is limited by ALOT...and if they are used to counter the usual facade set then well their attack will just go back to normal

Meteor Mash after flame orb= 75 damage Super effective hit- 150 damage
Meteor Mash without flame orb= 150 damage super effective- 300 damage

Facade after flame orb- 140 damage no type coverage

The reason why majority of the facaders are used is because they either have Guts or STAB from facade

Facade from heracross with Guts- 210 Damage
Facade from Hariyama with Guts- 210 Damage
Facade from Swellow with Guts- 315 or 280 i'm not sure how this one works
Facade from Ursaring without guts- 210 Damage
Facade from Metagross- 140 Damage


Overall metagross's attack is too high to be limited by one move and has far better choices from better moves, basically where would a facade fit in, that metagross cant do better and WILL NOT limit him after flame orb?

For those in the Ursaring group, Breloom can also work pretty well- Toxic Orb activates Poison Heal, it can learn Mach Punch for Weavile, and can use other moves like Stun Spore and Spore. It's also a little faster at 70 Base Speed.

what about this...

@Leftovers
Adamant
Ev:Hp & Att Max (or other better one...)
Guts
-Facade
-Night slash
-Rest
-Sleep Talk

...
So he can recover and abuse the sleep to take the Guts/facade boost...

Well, putting it that way, I guess you're right. Just Thought of posting an alternate set for a facader.

As for the Above ursaring

Facade Activates when there's Poison, Burn, or paralisis, and none of that happen's.Gut's activate's but then That ursaring Doesn't need facade taking up a slot when There's a ton of other, better move's to take advantage of Gut's such as:

Earthquake
Slash
Thrash
Close Combat
brick Break
Return

Or just about anything but, IN THIS CASE(and metagross's Case as well) Facade.
Not to mention a 1/3 a chance of screwing up and picking rest.

How about Slaking

Slaking@Toxic Orb
I can't currently think of an EV spread or nature right now
Yawn
Facade
Focus Punch
EarthQuake

The main Idea is simple:
First Turn
Yawn

Second Turn
Poison Seep's In And

A)They Switch out......B)They fall asleep
Third Turn:................Third Turn:
Facade......................Focus punch

And repeat.

I hope I helped.

P.S: I like Facade Breloom

If they switch Out, the Get a 210 base Power Facade at them.
If they stay, they fall asleep and Focus Punched.
Earthquake is just filler,That can be replaced by anything, preferably a dark or ghost type move

Lol don't understand? Ok imagine this: 1st turn, Slaking uses yawn. Opponent attacks. Next Turn, opponent switches (Well tell me who would wait for his/her Pokemon to sleep and get owned?) out to someone to COUNTER Slaking and it CAN'T move cos of Truant. Next turn, if the foe is faster(Most likely is...the better players will sure know that they'll get owned if they swicthed in something slower), it whacks Slaking with a Super Effective move and that's bb Slaking.

So he switches out, and bring's Bring's out, say Infernape.
He's got 75% Hp, And he's poisoned.
Infernape Use's close combat and at worst, Slaking live in the red and Counter's with Facade Which then OHKO's
The Infernape. This assuming a plus Def, Nature On Slaking Minus sp atk, And a Plus atk nature on infernape With Choice Band with a Minus sp def. In short, SLaking is Diehard.(That's not to say he won't faint afterwards though because of toxic, but you get the idea of how Beastly strong he is)

Ugh, well, it looked good on paper,(At least to Me) Then back to the drawing board for another good facader no one has thought of yet.

I Have it (At least I think I do)

Miltank@FlameOrb/ToxicOrb
Again, I can't think of an EV spread
Ability: Scrappy
Heal Bell
Curse/Brick Break
Milk Drink
Facade

This is Obvious,
Heal Bell And Milk drink When Needed
Brick break For those Annoying rock Types
Scrappy let's you Hit ghost's...
She Has Good Def's and And Atk.
I don't see Why not.

*Pray's So that this set Doesn't fail like the last 2*
