What is the skill combo for draven I cant seem to get it working for me

You blind them with your manliness,shoot a beam of DRAAAAAAVEN in their fave,hit them with a awesome DRAAAVEN axe of DRAAAAAAVENNESS,and they disentegrate from your awesomeness.

1) catch axes
2) .....
3) profit

1) ready axe
2) use e
3) use w
4)catch axes.

The most important part about Draven is to engage when you have two axes. It leaves you room for error and you can even get another axe by pressing Q again.

In general, you keep axes bouncing as you farm minions in lane. When you want to actually go in on a champion, you will use W to rush forward, throw the axe, try to catch the enemy with E, catch the axe, throw both axes, refreshing and moving toward them by projecting the axes forward. You will also usually fit your R in around the E, just make sure you don't knock them out of the path with E.

In terms of leveling, it is usually QWQE, then R>Q>W>E. You might also consider QWEQ if you will need the E at level 3.

Keeping your axes bouncing in lane forces you to hard push your lane, not entirely smart.

Not necessarily. The spin usually lasts long enough to stretch between last-hits. Also, you don't HAVE to last-hit the minions as soon as you're able to kill them. For instance, if you can deal 100 damage with an auto-attack, you don't HAVE to attack the minions when they reach 100HP. You can wait till they're at ~20 HP and not push your lane any harder than any other ADC.

If your spin is about to run out, and there isn't a minion ready to last-hit, then I don't think it's a huge deal to just let it run out and hit Q again. It only costs 45 mana, and you can probably keep it spinning long enough for that to regen on it's own. Alternately, you can hit an enemy champ, or the enemy tower if the opportunity presents itself. Or, you can just risk it and get an extra auto-attack on a lane minion before the last-hit. One hit worth of damage every now and then probably isn't going to hurt you too much anyway.

Slow them with ur Stand aside Ability, then activate Blood Rus,Use ur spinning axes to do bad damage to them, and finally finish them off with ur ult (Whirling Death).

Wait until they're out of position, speed boost to get in range, then knockback (or reverse if they're already in range). Ult if you have it, then follow up with some axes while repeatedly tapping W the whole time
