I'll fix/try to fix anything that seems over-powered.

I like the set, although personally I'd have liked it more if the last two stayed as tribute monsters rather than synchros, that's just a personal thing though, anyway, on we go.

 

Both synchros might be a little OP, Shadow Nimbus will almost definately always have a -minimum- of about 3800, both synchro materials and the one sent by his effect. Maybe have an upkeep cost of removing them from play or something?

Eye of the Storm will most of the time act as a 'once per turn, clear the opponent's monster field' remove the effect negation or multi-attack, both in one card, a beatstick no less, is crazy.

 

Other than slightly OP synchros the set is really nice, you seem to have kept to the general theme well (no battle death, risking lp from attack position and gain some advantage when swarming) It's a really good set and I think the OCG is pretty solid. I think you've really done a nice job with the whole Cloudian re-vamp here, maybe making them really usuable. Right now I'm going to give it a 6.5/10 ^.^
