the type of battler i am is a strategic type. i lke to surprise my opponenent wth every battle, no matter what. i never use the same team more than 5 battles in a row. and whats funny is i have 5 seperate teams!
now dark pulse, if garchomp can be used in OU, your'e current team, based on stealth rock and sun, can be easily over turned.
firstly i would send out a garchomp, and crunch youre claydol to death. you bring out ninetail, i use earthquake. you bring venesaur, i use fire fang. you bring darmanitain, i use earthquake, you use swasbuck, i use fire fang. and if you use kingdra. i use outrage. i suggest you rethink you strategy.
but good on you for thinking up this, it work's, but definetley need's some tweakng. maybe you could introduce some more type's of pokemon (e.g. ice type, electric [eelektross= noweakness]) or even just try to minimise your total weakness. i suggest a rain dance team with milotic in it. dont take any of this personally, im just giving you an unnoficial review.
though i use a trickroom set, i have 2 pokemon with a base speed of over 109 (starmie/ weavile), and i find it work's extremeley well against all battle types. full frontal offense, complete defence, mixed wall's, you name it. it can counter almost any set. i wont reveal the other 4 pokemon, for strategic reason's.
but i think you're set is really well thought through, and i congratulate you for it. :)
