As titled this is a combo deck based on
Kindo Shadowstep using
Tome of Horrors to repeatedly trigger Kindo's damage ability until he hits mastery or dies. If he dies you can bring him back that turn using
Sleeping Draught or
Immortalize or maybe an
Umbren Voidbringer. It usually takes two cycles through the Kindo/Tome loop to get mastery, but once that happens the game is usually over as their deck is now in their void. Everything else is there to draw into the combo, keep you from dying, or to put more cards in the opponent's void to feed Kindo. The two
Burglarize's are there to stop void hate. The combo seems pretty consistent and is relatively quick, but I've only played it in casual. Good luck and have a great day.
Also, why Immortalize instead of Dark Return or Last Chance? You don't have any decimate or exalted synergies.
