First build, so go easy on me.
So first,let me start with the point of this build. This is meant to work best in the jungle early game, as a ganker mid-game, and as a team leader late game. Voidsteel and Veteran give you stats that you need to survive fights on your own. AWard gives you the vision to help control situations. Cloak helps enable your teammates while giving a much-needed boost in attack speed. HotP shields allies when things go south, and Pearl gives your team the perfect getaway.
After my starter cards, I use these in the following order (according to slot): 1-6-3-5-4-2. Voidsteel and Veteran need to be completed before applying the next card, but feel free to add the other cards before upgrading them (none of the rest get an upgrade bonus).
When using this build, start with Gift as your ability, as the lifesteal helps you stay in the jungle to build difference-making power early. Get Light second and Judgement third. Obviously, upgrade your ult every chance you get. I tend to finish Gift before I even give a second upgrade to any of the others. Then, finish Light. Judgement is only really used to lock up opponents.
And that's all I can offer you guys with the build. Now all that is left is for you to go out there and master it.
