Kick, unfortunately I do not have a screenshot at this time but I can try to explain to you. When the game starts your screen would be centered to the top right of the map. There you would find multiple taverns with random heroes you can pick from for said game. When clicking on a hero, the hero's skill will get displayed, you select a skill by pressing on the "+" sign. In order to complete the picking of skills you are required to pick 3 normal skills and 2 ultimate skills where after you can select the hero model.
I hope this helps.
