A lot of guides 'work', that doesn't mean they're optimal. I have played a match as Taric using bravery items (I bought Mejai's Soulstealer, Sword of the Occult and Leviathan) and I still got a 7/5/12 score. Does that mean that it's a great build on Taric? No.
I have simply given my opinion based on how Irelia should be played, I don't need to test anything to comment on it.

Try incorporating some items with armor. This build might work well with a sunfire cape or warmogs

Why would you use AP runes on Irelia?
Also, with no escape spells and very little armor, you will get torn apart.

I really like this build i have tried it and i got a triple kill and survived ad carrys with mid HP.So Wayne3100 you dont cant launch a bad comment if you havent tried the build.

No.

This is not how Irelia should be played.
Rushing Trinity Force is exactly what you should be doing, but after that you get Youmuu's Ghostblade?
What you're doing is making yourself squishy while Irelia's best trait is that she can build tanky and still deal more than enough damage. Being tanky also allows her to dive into the enemy team and disrupt the enemy AD carry, in your case diving into the AD carry will simply get you killed.
Her Hiten Style passive heals are nice but definitely not worth increasing by buying Spirit Visage, Frozen Mallet is an item that she doesn't need since using Equilibrium Strike will slow - if not stun - your target and Irelia has high mobility anyway. Going for offensive masteries is bad since Irelia benefits more from Defense and Utility (0/9/21 or 1/8/21 to get the Cripple mastery would be the best setup) and not using Flash or Ghost means there's no escape from bad situations.
On top of all of that, you have a combination of runes that is simply laughable. AP Glyphs to increase your Equilibrium Strike damage, the ability that you max last?
Attack damage per level seals on a champion that needs nothing but Trinity Force to deal loads of damage? 2 AP Quintessences? What is Irelia, a mage?

I'm sorry but this is a really bad build, -1 from me.

oh my god ! i think you should think about other items Stark's Fervor isn't a good choice
