This is my goto deck every season for getting to masters. So far never failed, and getting a very high winrate with it so far.
Deck is super fun to play, as you have a lot of units that generates other cards, while also running solid threats that need answers.
The transform powers have surprised me as being super useful, as you usually don't need more than 5 power anyway. Only running 2 Tasbus, since getting to 5 shadow influence is not that easy all the time while running the faction less warp power.
Corrupt is an awesome card against any deck you suspect is running tempest.
I am debating on using 4x invoker maindeck instead of the mercanary, but torch is still a thing, and mercs are immune to anhilation. If you have the shoftstone i would try it out, as you do get to select better cards to draw rather than one random one.
