Assuming it's Hecarim jungle, you should always start machete + 4 pot and a yellow trinket
The default starting items are fine on Varus.
Hecarim is a tank, and building him with lots of health and armor is the way to go. He is also a jungler, so start with Spectral Wraith, Merc Treads. Finish off with Warmogs, Randuins, Spirit Visage, and a Ghostblade for some damage.
When Ekko was first released maybe, but not anymore.
Drumsticks.
Bananas.
Tear of the amumu.
Long sword.
In my opinion you should ban kassadin, hecarim, and yasuo. Other good bans are braum, leblanc, rengar and nidalee.
Doran Blade and health pot
Doran's shield or a pot combination
Don't start with doran's blade. It will be a GRAVESly mistake.
It has been on sale on halloween 2012 but is not for sale anymore
