[Uro, Titan of Nature's Wrath](https://gatherer.wizards.com/Pages/Card/Details.aspx?name=Uro%2C%20Titan%20of%20Nature%27s%20Wrath) is a 3 mana value with an Escape cost.

[Aluren](https://gatherer.wizards.com/Pages/Card/Details.aspx?name=Aluren) allows me to cast cards with mana value 3 or less without paying their mana costs.

Am I allowed to cast Uro, Titan of Nature's Wrath using its Escape ability and use Aluren to negate it's casting cost, requiring me to only exile 5 cards from my graveyard?
