This deck is largely a test to see what minion synergies work.
Synergies
Druid has some powerful 2-cost cards (Wrath and Wild Growth), but C'Thun often runs minion-heavy decks. Prince Keleseth may be able to boost those OK old god cards to great. Taunt and C'Thun also work well together, with the ridiculously good Dark Arakkoa and usually good Twin Emperor Vek'lor. Hadronox has a lot of potential value, and the other taunt cards help you get to the late game. Moat Lurker can proc Hadronox early, allowing for 2 massive board swings.
Under Consideration
There is some wiggle room because this isn’t designed to be entirely competitive. Given that, we can still refine it. I am not sold on Earthen Scales. Please feel free to comment with your suggestions below. Thank you for giving my deck a try!
I love the deck idea but why not dropping the keleseth theme and play instead the 2 mana 1/4 taunt grants c’thun taunt WHEREVER IT IS. should get c’thun to come back from Hadronox, if you play the 7/9 that gets back c’thun in your deck you can ress him with hadronox in double (or triple but would eb definitely too greedy) copy so you would be able to drop c’thun also as a threat and not only as win-con. obviously this requires a huge rework on the deck since you are again free on drops 2 but would keep the idea of the c’thun deck which could even work pretty well to me with those changes.
Tested the C’Thun w/ taunt interaction with Hadronox and unfortunately the latter does NOT summon C’Thun after it dies having been given taunt by Twilight Geomancer.
Hadronox summons only minions that have the Keyword TAUNT printed directly on them. For example, both 4/6 twin emperors are summoned by Hadronox’s deathrattle.
