Yeah, I understand. I gave suggestions without fully saying what I did to make them work. I use them in tandem with Planar Scout then the Shroud, later on try to get it to with Dark Transfo.
I run Planar Scour and Shroud on every deck seeing as it gives a bit of board presence, summoning ranged units far from the bulk of their own, making them pick a threat or to deal with dangerous things far from reach [things with Grow or ranged].
Lyonar has access to Sun Bloom though, a good disenchant AoE.
Redditors of Duelyst argue that Mechaz0r isn't even competitive viable and that some even want the progression to be 25% instead of 20% per mecha part. Thinking on it, Mechaz0r is easily counterable since most decks run ES.
I don't usually run into Mechazors since I'm a 20, and those that I do run into are those that are testing it. So far, all I need to do against them is just to pressure them into a corner while killing off the smaller ones. Mechadecks are usually predictable with cards that revolve around getting as much Mecha on the field as possible. The problem with Mechazors is that when the actual combined 'Z0r comes out, they have nothing left except their small ones.
Also, Crossbones.

Newbie here. Mechazor is a joke?
