Mage Bloodseeker

So, i saw a thread on reddit talking about dagon on blood and i decide to implement the build in a total mage blood thing.
The points he have are:

1)you can farm dagon very fast with a iron talon in the jungle
2)Enemy team will not pick invisible heroes, as you counter them, so izi jungle izi life
3)As you make space for a offlaner, you guys will have free kills when you turn 6

Dagon is very good on him because off bloodrage, if you do on him and you it will give ~~40% more damage or so, also you can get it very early

After Dagon 2 you should be aiming for the Euls Scepter, it will give the mana to give infinite sustain, give you the tp breaking thing and positioning for Bloodrite, its a must buy

Dagon 3 and then Hurricane Pike, this will give some good stats and the ability to force the push if someone is Ruptured

Dagon 4 and then pick your Aghs, by this time you will have more teamfights so rupturing 2 targets is one of the best things you can do, after you finish dagon 5.

So what do you guys think ? icefrog have been buffing this way of playing in the latest patchs, what are your thoughs ?

Idk it might work, but I think that the speed and his silence would be wasted
