Mecha’thun Hunter

I really wanted to make a Mecha’thun Hunter deck but after the Hunter’s Mark nerf, I didn’t know what to do. Your combo will be to play Oblivitron, kill it, summon Mecha’thun, Hunter’s Mark it and kill it. You will be drawing cards with Ursatron and Arcane Fletcher. Tracking is more for after you draw your combo pieces. Vereesa is for killing enemy minions and controlling the board. By no means am I a professional deck builder, so constructive criticism is always appreciated.
