There might be a bit in the way of coverage moves that could be streamlined. Most of the team are a bit eclectic at present. The Gogoat is decently set up, at least, however some of the Pokémon such as that and Jolteon might be dependent on context.
Is the plan here for singles or doubles, primarily? In certain contexts, the latter is primary, in part because it makes most teams look more solid as display goes.
Agility on Jolteon may be problematic unless you're planning for a Baton Pass set-up, for instance with the Charizard. Special Defence there might be less determinate, so make sure you have an overall plan there. It would have to be protected a bit from physical attacks, and might not be as effective as a stall because it can usually go down quite easily.
There's a lack of status effects at the moment apart from Blastoise, which is a slightly strange place to focus this element. Which are allowed will depend on the context, nonetheless usually you could use some.
The Charizard might lack focus somewhat. Usually a Charizard-X combination might focus on attacking, rather than having to do both special and physical damage.
With Garchomp, is the plan to set up with Swords Dance, or instead to attack with moves like Outrage, etc., from the off? It's quite focussed on attack, comparatively, so these may work. It looks to be aiming for more of a set-up option, as it is slightly protected, but it can still be quite vulnerable to the right moves. Presumably the other moves would then probably be focussed on a specific modus operandi like Earthquake, etc., or something more secure - in which context, with Substitute or such it could be quite efficient. That and the Charizard look like some of the stronger, more blatant attackers of the team, and the rest could probably try a support role. However, generally, the team doesn't tend to use that much by way of highly inaccessible types, like Steel or Fairy, and hence using the others to support these - for instance with Paralysis moves, etc. - and shield them, before allowing them to take down an opposition, would generally be more efficient. The Gogoat, along with say a status effect causing Pokémon alongside it, and perhaps a more secure type in the wings - depending on how well this initial set-up goes - might be enough to generally support the others, if that were necessary.
When it dawns that Keats' idea of 'negative capability' is basically reducible to the public perception of Lucario.
