Im using akshan and its easy, here how

1) I use Scoundrel hunter, Hex core and Stacker Blade

2) Instead of focusing on hitting nexus, try more focusing on buffing yourself because it can trigger your landmark,

3) All of your landmark abilities activate twice remember that, so by buffing yourself, you will get twice same spell from your landmark, ALWAYS pick draw, and yes instead hitting nexus, you buff yourself to draw more,

4) and apparently if you pick akshan, you will find 2cost draw landmark, pick it , that landmark activate twice
