The deck’s shell is really similar to Cubelock, so before you say “Why don’t you just give up on these stupid combos and play that instead?”, know that you should play Cubelock competitively, and you should play this deck for fun.
Finally, kill the cube with a Dark Pact, Shadowflame, or with combat damage, copy a Clockwork Automaton with Faceless Manipulator, and go face for a minimum of 24 damage (and 48 healing!), depending on how many other Clockwork Automaton‘s and other minions you have out to attack with.
Of course, silence can really hurt this game plan. A silenced Cube or Automaton can mess things up big time. It hasn’t happened to me yet, but I rue the day.
So far, I’ve had some success without the full combo, by doing things like dealing 6 and healing 12 over a few turns with just one Automaton.
Like I said earlier, this deck likely won’t beat Cubelock or Baku Hunter (Although I have beaten both even and odd Paladin), but it generally works and is a lot of fun to do an unnecessary amount of face damage for the win.
