PROS:
1) Very Reliable Crowd Control
2) Superb Lockdown Mechanism
3) King of the Teamfight

CONS:
1) rely on Echo
2) long cooldown
3) Not really tanky in early-mid game


HOW TO PLAY USING THIS BUILD:

1.) Aim to delete enemy's carry first in the teamfight.



2.) Create this Double Circle Gauntlet in the middle of the crowd,
make sure there is enemy's carry within your gauntlet range:

let your teammates finish him!



3.) Reflex Block & Crucible can be very troublesome,
Use Nullwave Gauntlet if it necessary.



4.) You re not a primary damage dealer here, even if you use the Aggresive build.
your primary goal to HELP your teammates stay alive as long as you can in the middle of teamfight.
Secure a kill is your secondary aim.


5.) Do not use ur gauntlet if your echo are in cooldown, unless you have to use it for saving ur teammate

That's all folks!
Sorry for bad English btw ^^
