So, I built this deck with intent to meme on my opponents, figuring I wouldn’t really be able to drop Mechazor! frequently enough for it to actually win.

Then it did.

The basic strategy of the deck is to spam out the Mechazor! pieces, especially Sword, Blaster and Silica, as quickly as possible. Cosmic Flesh can turn Chassis into a fairly effective wall as well, Wings is a good early draw since you can pop a bubble with it and then drop a Scion’s First on it to get a 2/5 on the board alongside your Mechazor! progress, or a Helm to get an extra 20% progress. Helm’s job is to be cheap and easy to spam, it is honestly expendable, just there to get you that 20% Mechazor! progress and be in the way for a turn. Alter Rex’s job is obvious, stay back so you can get an extra Mechazor! when you pull one off. You typically want to deploy your Mechazor!s near the back of the battlefield where they can make the most of their range while being difficult to swarm and kill.

Arrow Whistler’s job is to boost the power of Blasters, Mechazor!s, and the two Vale Hunters, which are mostly meant for support, as they are great for killing Wraithlings and popping forcefields.

Orb Rider’s job is to bounce Mechazor! progress cards back to your hand so they can be played again, especially Helm, for its cost efficiency, or Silica for its massive boost to Mechazor! progress.

If at any point you have no Mechazor! pieces or Silica’s in hand then the best option is to replace something you have and activate any copies of Scion’s First that you’ve got. With 18 minions that contribute to Mechazor! your odds of pulling one when you replace are pretty good.

Sajj herself is not the most useful commander in most circumstances, but on occasion you just REALLY need to get rid of a 3 or 4 health minion, or knock 4 off of a much bigger minion, making Psionic Strike a very useful, if situational, tool.
