Unlimited Rain Dance showing its age

[Starstorm]

This has been my signature deck since Base Set. It's frighteningly powerful, and can draw through itself with ease. But there's one chink in the armor that shows the deck's age. Today's EXs far outclass the ones from days of yore. My main hitter, Suicune EX, has 100 HP. Darkrai with a Dark Claw or a Special Darkness Energy 1HKOs this for two Prizes, and only allows for a revenge kill if I put every Energy in my deck on Suicune. This seems like a major problem. Any help I can get adjusting this to better deal with today's Pokemon is appreciated. That said, here's the list.

POKEMON
4-1-4 > Feraligatr Prime (HGSS)
4 > Suicune EX (Team Magma vs. Team Aqua)
4 > Cleffa (Neo Genesis)
1 > Kyogre EX (Crystal Guardians)

TRAINERS
4 > Professor Oak
4 > Computer Search
4 > Misty's Wrath
4 > Rare Candy
4 > Item Finder
4 > Fisherman
3 > Broken Time-Space
2 > Windstorm

ENERGY
13 > Water Energy

A lot of your cards have been reprinted:

Professor Oak = Professor Juniper
Item Finder = Junk Arm

Cleffa neo genesis is similar to HGSS Cleffa.
Windstorm is a little like Tool Scrapper.
We have a new Kyogre EX but less awesome
We need a new Suicune

Anyway this is a cool deck. If you want something new look into Keldeo EX, which unfortunately, doesn't come for 2 months. A little far off but worth mentioning. Also a couple Catchers wouldn't hurt.

Well that's the old power creep problem, though it's got really bad since Black & White. You could either swap Suicune ex for a new EX like the upcoming Keldeo EX or play a different version of Unlimited, which might be better anyway as you won't have to play against Porydonk or broken lockdown decks.
A version of Unlimited that's been becoming popular is the 150 format, the new EXs (B&W series) are banned so it means a lot of the old cards are still playable. See the links in my sig, our League has done a few articles on it so far.

You could even go back to using Base set Blastoise, it works really well with this Blastoise (Unleashed) for 100 snipe every turn and Suicune ex will still be decent, uncapped damage is always a good thing to have! Feraligatr Prime is still a good option though, you could also use the regular Feraligatr from the same set and go with a more spread based strategy.
