Usually you would want to shove lane and get level 2 as fast as possible because Draven has additional 100 AD level 1, when playing with thresh the best possibility is rush level 2. DONT FOR GET TO ALWAYS KEEP 2 AXES IN LANE!!

Once you have your core items Infinity Edge and Phantom Dancer, it would be best to stay mostly in the back and keep 2 axes on at all times. Usually with these items you can duel with the enemy AD or their mid lane.

If it comes down to late game, you would want to buy Furor for the extra movement speed every attack, you can also get Trinity Force. When it comes down for you getting caught you would have to either duel or let your team get objectives. (DON'T GET TRIFORCE UNLESS YOU ARE FED!!)

Always have 2 axes on throughout the game, when you have 2 axes your additional damage will do about 200 AD

Ok the main thing about Draven is his axes cause it gives him additional 200 AD full built, when in game you can guide the axes by walking side to side which can control the movement plus they leave a marker on the ground to help you. But when chasing an enemy it traces your steps and falls right in front of you to keep catching it

Dravens ult is like Ezreal's, Ashe's and Jinx's, but his ult can come back to him. But when guiding the ult back to him you have to walk the direction you would want to aim it. For example when ulting someone and they side step it, if you do the same if will come back and get the kill. But the thing about his ult is that when it hits an enemy it immediately comes back.
