Very interesting mission.

Yes, ward isn't a big advantage against MJ Deception. 12 wins isn't too bad, maybe you should try later when Meta is different.

I wanted to try Atlantean Deception in winter (I was learning GU that time, exploring everything). I bought 2 Rolling Watchers and 1 Spiral Golem + Phased Touch Golem was neutral... Then, I realized the archetype was too expensive for me and I stopped the project.

I still have 2 Rolling Watchers in my collection. They are too cute to sell them :) Maybe one day, I'll try a Magic deck with Rolling Watchers, Undertow Rovers, Phase Golems + Oni Spellswords, Choralis and other good creatures from any tribe...

My last WR reward consisted of 25 MJ cards and I only had 1 shadow :(
