Its kinda hard to say which is better. Depends on what are you meeting on ladder. But you have 4 taunt-givers and taunts as an advantage Of shambler doesnt matters that much. But exept sylvanas and rag, all Of your minions are strong just because Of their stats, so in the most cases shambler is easier to make it good than manipulator. As for Me, shambler is better versus aggro and manipulator is more like combo-control card.

My favourit deck in hearthstone. Really.

Soulfire is helping with totem golems, azure drakes, tomb pilagers, and other dangerous things just for 1 mana. It can also help you with killing your opponen in the late game through the taunts. Its a cool card, and leeroy combo is just not needed to win now. Shamans, Hunters, warriors, all theese guys would lost the game if they losted the board control, so your plan is fight for board, not slow-otk-leeroy-combo.

I mean, i agree* espesialy about Harrison)

I am so glad to hear this!? You are wellcome, friende? i thought about similiar replayes, just like you. I after, espesialy about Harrison, which , as i think, is still a tech card, that is not help you in everyday situation) so, good lucky to you!
