New item for Aatrox

Honestly, Aatrox is really not that bad...but he doesn't get the benefit if super items perfectly syncing with his kit like Irelia does with Trinity Force, or tanks scaling off of all the great armor items. It seems like every mage tank and tons of fighters get the benefit of spell blade. But none of the items that give it are any good for Aatrox.

Item I'm proposing is a Rapier and Main Gauche (a quick light weapon and a defensive parrying dagger). Here are the stats (obviously just a general idea):

50% attack speed 40 Armor 20% cool down

Unique Passive--– Spellblade: After using an ability, your next basic attack (on-hit) deals 100% base attack damage and grants 30% reduction of all incoming damage for 3 seconds.

Or something like that. I think that this item would benefit Aatrox, helping him not have to choose between being tanky, attack speed or AD. With this he can satisfy his attack speed needs in one item and help him not be so squishy due to the bonus armor and damage reduction.
