This comp revolves around the 3 Legend units and looks to buff up Volibear as much as possible with Dragonmancer units. This comp is great as you can flex with both Attack Damage and Ability Power items for Volibear and Anivia respectively.
This comp is fairly simply to force. You can have very flexible items to itemize either Volibear or Anivia. Augments are flexible in general, as you don't need anything specifically. If you can find Volibear / Anivia easily in the mid game, you can take that as a good sign to go for this comp.
Level up to 4 early if you want to start a win streak. Level up to 5 to try and continue the streak.
If you're weak in the early game, you can opt to save gold and lose streak instead.
At Round 3-2, level up to 6 regardless of your start. Put together the strongest team you can.
At Round 1, level up to 7. Roll down to stabilize your comp if you are weak.
After hitting level 7, slow roll for Volibear/Anivia 3. Level up to 8 after you hit one of these units. If you are strong and have lots of gold, you can wait until level 8 before slow rolling, but this is risky.
You can easily transition from the early game with either attack damage or ability power items. Ezreal is a great early game carry that can use either type of item so let's build around him.
Once you find Volibear and Anivia, you can transition toward them and the final comp, but it won't be near complete until you find Ornn.
A good item to use in Legend comps is Chalice of Power. By placing this on a unit being absorbed by Anivia, you will be able to double dip. You will get the bonus AP from the item, and the Legend trait will also grant more AP from absorbing a unit that is holding Chalice.
Before going into 6 Dragonmancer at level 9, you can also run 6 Jade at level 8 by running Shi Oh Yu. Once you hit level 9, you can then look to pivot toward 6 Dragonmancer.
Gain 5 gold. At the start of every turn, Champions in your 3 rightmost bench slots transform into random Champions of the same cost.
Gain a free Shop refresh each round.
When the Dragonmancer Hero gets a takedown, champions that share a trait with the Dragonmancer Hero gain 70% Attack Speed for 4 seconds. Gain a Ashe.
