Pokémon team advice for Elite 4 and Champ.?

[~Fallen~]

My team right Now:

Name: Absol, Lv. 53, Item: Exp. Share (for training), Moves: Night Slash, Future Sight, Sucker Punch (keeping), Shadow claw.
Stats: HP: 142, Attack: 150, Defense: 66, Sp. Attack: 93, Sp. Defense: 78, Speed: 86.

I replaced my Stoutland for this guy, who's a level is a LOT Lower than this absol's. I replaced slash (I don't know why, it's a good move) for Night Slash.

Name: Enbuoh, No item, lv. 74
Moves: Head smash, Arm thrust (the only fighting type move it leaned >.<), Bulldoze, Flare Blitz.
Stats: HP: 254, Attack: 251, Defense: 122, Sp. Attack: 149, Sp. Defense: 138, Speed: 134.

My starter. I'm never replacing him. Ever.

Name: Zekrom, No item, Lv. 63,
Moves: Dragon claw, Draco meteor, Flash, Fusion Bolt.
Stats: HP: 203, Attack: 218, Defense: 163, Sp. attack: 157, Sp. Defense: 132, Speed: 146.

I'm possibly going to keep Flash, but give me your opinion...

Name: Volcarona Lv. 71,
Moves: Fly, Quiver Dance, Heat Wave, Bug Buzz.
Stats: HP: 221, Attack: 107, Defense: 111, Sp. Attack: 213, Sp. Defense: 153, Speed: 171.

I don't know about this one. It mainly has bug type moves, but all of them are pretty good. Heat wave is okay....

Name: Exploud, Lv. 63, Item: None.
Moves: Stomp, Uproar, Hyper voice, Crunch
Stats: HP: 207, Attack: 134, Defense: 96, Sp. attack: 134, Sp. Defense: 76 Speed: 105

Replaced Unfezant for Exploud. I'm possibly going to replace Uproar for a different move...What do you think?

Name: Rotom (It's supposed to be in it's frost form, but the site I got this from didn't have any of it's other forms, so I had to use it's normal form. I got it from an NPC, by the way...), Lv. 65 , Item: None.
Moves: Electro ball, Hex, Discharge, Blizzard
Stats: HP: 150 Attack: 102, Defense: 139, Sp. Attack: 153, Sp. Dfense: 177, Speed: 129.

Okay. I might be able to beat the E4 if I train him more, But should I replace Rotm for another...? It's level 65 now.


That's my team. Tell me if I should make an changes. I've got other Pokémon from the Pokétransfer and massive outbreaks. (I have plenty of Pokémon in my box, too.)

(I'm going to be editing this to match with their moves and levels and replacement Pokémon...)
