Hi Alexwolf! This is quite a awesome team you got here using the infamous deo/gar/weavile core, and the pairing of kingdra and breloom makes this team very solid! Your kingdra set, I really like it, as ice beam is actually quite good on kingdra, but the lack of draco-meteor is pretty unappealing as kingdra wont be able to break through some bulkier waters. I know that you like to use kingdra as a late game cleaner so heres a set that after it uses d-meteor, kingdra can still continue its sweep. Classic mixdra set!

Kingdra @ Life Orb
Trait: Swift Swim
EVs: 40 Atk / 240 SAtk / 228 Spd
Mild Nature
- Rain Dance
- Draco Meteor
- Waterfall
- Hydropump/surf/(anything really)
Draco meteor allows you to break the common water switch in, and than continue your sweep with rain boosted waterfalls, killing most of the metagame after some rocks and spikes damage. The last move is up to in all honesty. Anyways cool team and luvdisc'd!
Edit: Was just ninja'd by you lol, so don't know if this rate is still relevant, hope it helped.
