Good Competitive team or no?

[haxRus]

Ok guys, heres one of my first competitive teams, i have a sandstorm one but honestly, who doesnt. Anyway, here goes:

Conkeldurr
move 1: Bulk Up
move 2: Drain Punch
move 3: Mach Punch
move 4: Payback / Stone Edge (don't know which)
item: Leftovers
ability: Guts
nature: Brave / Adamant
evs: 120 HP / 252 Atk / 136 SpD

Next is Heatran:
Shuca Berry Naive
Moveset
~ Stealth Rock
~ Fire Blast
~ Earth Power
~ Explosion
252 SpA / 4 SpD / 252 Spe
This heatran is a lead, setting up rocks and then exploding

Next is Jirachi, which is a wish supporter mixed with a serene grace flincher.


Leftovers Jolly
Moveset
~ Substitute
~ Thunder Wave / Body Slam
~ Iron Head
~ Wish
164 HP / 168 Atk / 176 Spe

Now there is a bulky reuniclus, which is a good special attacker and wall
[SET]
name: Calm Mind
move 1: Calm Mind
move 2: Recover
move 3: Psychic / Psyshock
move 4: Focus Blast
item: ?
ability: Magic Guard
nature: Bold
evs: 252 HP / 252 Def / 4 SpD

Next is the infamous garchomp, which i am willing to change around if the need arises. this is just the basic set, Yache Berry Swords Dance set with Fire Fang Outrage and EQ, ev's obviously 252 ATK 252 SPE 4 HP

The final member of the team is unknown, i was thinking a special wall or a sweeper like latios. Any help is appreciated. Thanks :)

Life Orb is a must on Reuniclus; it gets the power boost, but no recoil thanks to Magic Guard.

Latios could be good:
-Trick
-Draco Meteor
-Hiddden Power (Fire)
-Surf
Nature:Timid
Evs: 4 HP/252 SAtk/252 Spe
Item: Choice Specs/Scarf

If you don't like Latios' Pursuit weakness, try Hydreigon:
-Draco Meteor
-Surf
-Fire Blast
-U-turn/Dark Pulse
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Choice Scarf
