COC working with Nvidia shield Controller?

[morenick]

Nvidia shield tablet got a built in button mapper, even if the game does not have controller support, you can still map the buttons on the screen. You can play even arcane legends with controller on an nvidia shield tablet +shield controller, no need to root and install any app, just long press the triangle (start) button on your shield controller in any game.

Like this:

You can play AL on xbox? O.o

Nope I guess its the nividia shield controller
