6th Gen Your first Champ team.

[Rezu]

Aegislash (Excalibur)
Shiny Greninja (Shadow)
Snorlax (Nope)
Chesnaught (Skolldir)
Blaziken, which i never really used
Flygon (Jetstream)

They were all lvl 76-79 except for Mr. Speed boost who was already 83, despite I left him on the pc for a couple of gyms and never really used him

 

[Fourth The Tyrant]

My first victory, first playthrough was with my super unbalanced team consisting of:
Lhazuli the Delphox
Yalah the Talonflame
Morokei the Charizard
Zira the Female Pyroar
Krosis the Lucario
And King the Tyrantrum

I didn't plan the team at all. 4/6 fire types just sorta... Happened. Just used the ones I liked that I saw. :P Fun though!

Oh, and they were all mid-60's.

 

[Altair1]

I don't exactly remember the levels... They were kinda high though.

My team in X consisted of Greninja, Klefki, Aurorus, Hawlucha, Barbaracle and Gogoat.
My team in Y included Delphox, Pangoro, Dragalge, Noivern, Sylveon and Tyrantrum.

 

[PhoneHome]

Will be able to update this tomorrow with my team...

 

[Pinkie-Dawn]

My first champ team was Raichu, Sylveon, Tyrantrum, Gogoat, Blastoise, and Delphox. All of them being at lvl 69.

 

[AllergicProductions]

I was juggling twelve Pokémon for most of the main story, but in the end I decided on these six:
Chesnaught, Blastoise, Ampharos, Pyroar, Florges, and Furfrou. I don't remember the levels off the top of my head, but I know they were all around lvl 63-64 by the time I reached the champion.
For the record, the six I didn't choose were Aurorus, Lucario, Lapras, Talonflame, Aegislash, and (shiny) Diggersby (which unfortunately became an HM slave T_T).

 

[Charizard17]

In Pokémon X, I beat the Elite Four with Delphox, Pangoro, Goodra, Charizard (Mega Form X), Lapras, and Crobat.

 

[Natnew]

my first team... just beat it yesterday

 

[Mr. Flix]

My first team was
Gardevoir 76
Charizard 71
Lucario 68
Roserade 64
Aurorus 80 (Because it was traded)
Greninja 67


Aurorus made the Champ really easy, so many Ice-Weaknesses o,O

 

[Cameo]

I had Delphox, Lucario, Abomasnow, Gardevoir, Salamence and Bibarel as a HM-slave. :P Nowadays I mainly need only Gardevoir and Blaziken. With Gardevoir you can basicly wipe everyone's team if you use Mega Evolution and the right moves and Blaziken easily wipes the Champion under three minutes. :3

 

[She_Delphox]

I had the following team when beating the Elite Four for the first time,
since I got my Pokemon X game I wanted to have an all-Kalos-Pokemon team for the first time :) :
- Delphox
- Goodra
- Clawitzer
- Aurorus
- Noivern
- Sylveon

I have had no problems at all, Sylveon and Delphox saved my *** a lot of times there! :3

 

[Timmetje]

I beat my first sixth gen game (Pokemon Y) with

- Greninja
- Lucario
- Drifblim
- Tyrantrum
- Abomasnow
- Granbull (Gotta have a fairy type no?)

 

[Ramsie]

I first beat the league with this team:
Aries the Deplox
Roosevelt the Sylveon
Sperry the Lapras
Florizarre the Venusaur
Rex the Tyrantum
Athena the Doublade (Eviolite is great!)

I feel like my team was pretty standard, but I really enjoyed playing through with them.

 

[Death]

My first game clear was with:
Aramis my Aegislash
Pavlov my Lucario (from the wild)
Tiny my Tyrantrum
Damian my Talonflame
Fabio my Furfrou
Pascal my Greninja

To this day, Damian still goes around with me as my Lv. 100 Egg Incubator + Transportation Pokemon.

 

[Capitão Coffee in Hell]

Pokemon X:
Chesnaugh, Charizard, Heliolist, Clawitzer, Aurorus and Malamar

Pokemon Y:
Delphox, Dragalge, Blastoise, Talonflame, Gogoat and Pangoro

 

[Stokesma]

I defeated the Elite Four and Champion with these Pokemon for the first time:
Espada the Chesnaught
Kamblast the Blastoise
Soul Calibur the Aegislash
Tyrantum
Nala the Pyroar
Princess the Nidoqueen

I had trained over 30 different types during my playthrough that it was somewhat hard to choose which ones would be in the final fights.

 

[Hainline15]

I ended up beating the pokemon league the first time with

Pidgeot- Level 71
Druddigon-Level 60 (filler pokemon)
Gallade-Level 68
Blaziken-Level 81
Venasaur-Level 71
and my lovely shiny Seadra-Level 66!

 

[AdamantSpiritomb]

X-

Blaziken
Alakazam
Xerneas
Lucario
Delphox
Blastoise

Y-
Electivire
Garchomp
Sharpedo
Dusknoir
Mewtwo
Rhyperior

 

[Sandslash Fan]

Furfrou
Xerneas
Chesnaught
Blaziken
Blastoise (MVP)
Chimecho

 

[Hikamaru]

My team is right here:

They were all quite strong attackers in their own right, but they all did get involved battling an Elite Four member at some point. My real star against the Champion would have to be Roserade, she survived a Mega Gardevoir's Psychic so I could land super-effective Poison attacks on it. Greninja and Sylveon were also taking part in those late battles a lot as well.
