[Gameplay help] Itemization Vs Ekko?

What are the best stats to buy against the meta Ekko in top lane?

I mostly play Tanks and Juggernauts and the current meta shift that favors the ranged top laners is painful, but Ekko continues to be a rather large problem in the laning phase.

His base kit is magic damage. Fervor provides him a truck of AD type of damage. He builds tanks and usually no damage outside Trinity Force.

What to build against him? AR?MR?Both?
