Is this a good team?

It is a great team 8/10 level up your pokemon

Kyogre you have the perfect move set for this pokemon

Banette it's an ok moveset

Crobat good moveset there

Metagross when you can teach it metor mash

Swapert should have surf, muddy water, ice beam and earthquake

Rayquaza good moveset you have there

Since you have a Kyogre, I suggest you switch your thunderbolts with thunders.

It's not good, but it's not bad either, at least in terms of the crappier teams I've seen b4, id give it a 7/10

Its not bad I would give it a 7/10.

It is a good team but why do you have rayquaza dragon dance change it.

Not bad.5/10

You're team is pretty awesome for the current levels;

Here's my advice (I'm a dragon master so my advice might be a bit crook accept for rayquaza)

Kyogre; Fine by my standards.

Benette; Needs more ghost/pshycic moves, will-o-wisp isn't very good as a burn only takes away about 6 hp per turn.

Crobat; Pretty good, i've got no advice to give for it.

Metagross; Iron defence is C%@#! Replace it with a decent steel move

Swampert; Needs way more water moves, Swampert is water/ground so it receives a 1.5x power boost when using water/ground moves. Teach it Water Spout instead of endeavour; Surf instead of muddy water (Surf is way more accurate.) and give it Hydro Pump instead of Brick Break.

Rayquaza; Lightening moves a real bad on Dragon Pokemon, replace it with a move like extremespeed or dragon breath, Dragon Dance is a good move don't replace it as it raises speed and attack and is very good in long battles. Crunch needs to be replaced as it is a dark move, I recommend flamethrower to eliminate any Ice challenger that stands in your way.

Oh yeah I rate it 7.5 / 10 (Mainly because of the levels (-.-) )

Hope I help!

Pleeeeease get rid of banette, it's useless, just like all the other ghost Pokemon except shedinja(which I got lv. 100, my brother had banette lv 100 and it knew, thunderbolt, shadow ball, faint attck, will o wisp, and it couldnt beat the elite 4 by itself(which all his other lv 100s could do, don't be a fool and waste yo time training it

Take my advice.
