Looking for tips on my team for improvement.

[DracoCharizard]

Hey everyone, I recently decided that I wanted to start battling again. I just entered my team that I would like a little help with in the upcoming pokemon wifi tourny.
I honestly don't know a lot about excess synergy other then basics, and held items I am still working on getting to know. Bear in mind that the Wifi tournament is double battles only.
However, here is my Rain Dance Team :

Ludicolo - Leftovers - Bold Ev- 252Hp/216Def/40 Special Def
Rain Dish
*Substitute
*Leech Seed
*Protect
*Giga Drain

Ludicolo's primary partner :

Floatzel - Shell Bell - Adamant Ev - 252Attack/232Hp/16 Special Def
Swift Swim
*Ice Punch
*Taunt
*Waterfall
*Rain Dance

Toxicroak - Black Sludge - Adamant Ev - 252Hp/252Attack/4Speed
Dry Skin
*Sucker Punch
*Fake Out
*Drain Punch
*Substitute

Kingdra - Nevermeltice - Modest Ev - 252Special Attack/192 Special Def/64Hp
Swift Swim
*Ice Beam
*Draco Meteor
*Rain Dance
*Surf

The last two spots went to electric types that can take advantage of the Rain

Thundurus - Expert Belt - Naive Ev - 252 Special Attack/252 Speed/4 Hp
Prankster
*Hammer Arm
*Thunder
*Heal Block
*Dark Pulse

Jolteon - Razor Claw - Naive ( Timid just woulnd't pop ) Ev - 252 Special Attack / 252 Speed/ 4 Hp
Volt Absorb
*Volt Switch
*Thunder
*Rain Dance
*Hidden Power

Any and all criticism/help would be appreciated, and again --- Held Items I don't have many yet, and am still working on getting my BP for them.

Have you considered using drizzle politoed?

I had thought about it, but I was under the impression thjat drizzle politoed was banned from the tournaments along with drought ninetales. Unless that is for a different set of tournaments in which case I will be kicking myself in the butt >.<

*Thunder
*Heal Block
*Dark Pulse

Why are you using heal block on Thundurus? Taunt can do a similar job by stopping them from using Recover etc. (I know Leftovers etc. is uneffected by Taunt and Heal block hits both opponents, but still...)

That was actually the primary reason I decided to go with heal block, simply because it does effect both enemies. But I agree, taunt could work as well

While Taunt doesn't effect both opponents it does stop Trick roomers which could RUIN your team:I know because I have ran a TR team.
