Was playing against Karn. While it did not happen until turn 3, clearly the deck has the ability to do this. Have seen it go land, mox, mox, mox on the play so clearly can cast cast Tinker turn 1 on the play then drop Darksteel Colossus before you even draw. What a sight T1 11/11 with trample and is indestructable. Craziest boss deck yet imo.
