What are three good Pokemon to support Articuno, Zapdos, and Moltres? I want to use these guys on my team, but I want to make sure I have the approporiate backup for them. If this isn't suppose to be on this board, then you know the drill. Thanks.

You'll want a Claydol or a Flygon to absorb all Rock and Ground attacks.

Snorlax/Blissey to absorb Ice Beam.

This?

{moltres}{zapdos}
{snorlax}{blissey}

Or did you mean Snorlax OR Blissey?

I actually wouldn't recommend using all three birds on a team. Ho-oh has a wider movepool than moltres, Raikou isn't hurt by ice beam like zapdos is, articuno is ok if you're going to 2HKO everyone.

Ho-oh is uber, Zapdos is gets Ground Immune, and Articuno won't be offensive anyway.

I see the team as

Zapdos, Moltres, Articuno, Snorlax, Claydol, Celebi

CB Zappy, Sp.Sweeper Moltres, Heal Bell Cuno, Curselax, Standard Claydol and Celejump.

Zapdos may be ground immune, but Raikou can get reflect to guard against EQ. Also, if we're talking metagame and not GBA, you can give it: Reflect-Calm Mind-HP Ice-Thunderbolt.

U|33r 1337 Special Sweeping.

...he didn't ask about Raikou. He asked about Zapdos. He asked 3 good support pokemon, not if it was a good idea.

Also, I've tested. The Birds + Lax + Claydol + Forretress = GREAT team.

I'll suggest this:

CB Zapdos
Special Sweeper Moltres
Cleric(if you have XD)/SleepTalk Articuno
Curse Lax
Standard Claydol
Spin, Spikes, m00b Forrey

Since this in this forum I'll post the team Netbattle Style:

Zapdos @ Choice Band ** Seymour
Trait: Pressure
EVs: 252 Atk / 200 Spd / 56 SAtk
Naughty Nature (+Atk, -SDef)
- Drill Peck
- Hidden Power [Fighting]
- Sleep Talk
- Thunderbolt

Absorbs Sleep, Thunderbolt still does nice damage to things weak against it.

Moltres @ Leftovers ** David
Trait: Pressure
EVs: 60 HP / 252 Spd / 172 SAtk / 24 SDef
Modest Nature (+SAtk, -Atk)
- Flamethrower / Fire Blast
- Hidden Power [Grass / Ice]
- Morning Sun
- Sunny Day / Sleep Talk

CRAZY powerful.

Articuno @ Leftovers ** Todd
Trait: Pressure
EVs: 188 HP / 132 Def / 56 SAtk / 132 SDef
Calm Nature (+SDef, -Atk)
- Heal Bell / Sleep Talk
- Ice Beam
- Rest
- Roar

It can take special attacks that aren't Fire and Electric and has Ground Immune. Roar for pHazing is fun.

Snorlax (M) @ Leftovers ** Love Handles
Trait: Thick Fat
EVs: 204 HP / 44 Atk / 136 Def / 124 SDef
Careful Nature (+SDef, -SAtk)
- Body Slam
- Curse
- Rest
- Shadow Ball

This will take Fire, Electric, and Ice with no problems.

Claydol @ Leftovers ** Bryan
Trait: Levitate
EVs: 112 HP / 96 Atk / 108 Def / 96 SAtk / 96 SDef
Relaxed Nature (+Def, -Spd)
- Earthquake
- Ice Beam
- Rapid Spin
- Rest

For the DDtar or the generic CB with EQ and Rock Slide.

Forretress (M) @ Leftovers ** Fort Knox
Trait: Sturdy
EVs: 116 HP / 142 Atk / 252 Def
Impish Nature (+Def, -SAtk)
- Earthquake
- Rapid Spin / Rock Slide / Rest / HP: Bug
- Explosion
- Spikes

Since Claydol spins this guy has an option there. Spikes + Sp.Atk of those Birds = hurt.

how about:

Moltres
Articuno
Zapdos
Swampert (Pwns rock types)
Blissey (Heal Beller/SP. Sponge thing.)
Umbreon (simply coz it's an awesome tank)

That is a team that lacks physical attack power and gets walled by Celebi + Snorlax fairly easily. I'd drop Umbreon for Heracross/Salamence and Blissey for Snorlax.

Umbreon is just a lovely wall that's meant to support and help set up for a team. You really should consider dropping moltres, as it really doesn't do anything for your team.

Then it wouldn't be a Legendary Bird Team...

Seriously, Moltres can Wisp, Sleep Talk, and/or just have CRAZY Fire damage. Also, Moltres can ABUSE Sunny Day like no other pokemon....save Eggy.

Umbreon would mainly be walling damage and passing Wish+Mean Look...Trapping isn't so much needed and with the massive EQ immunity, they can switch-in easily.

Umbreon CAN be used...but Snorlax does a better job at taking the Ice attacks(thick fat).
