Most of this list is directly copied from @RingSlayer 's Iron Savior with only a few modifications. Here I share some impressions after some initial testing and taking it to our local Cornerstone event.

Discussing modifications:

Added Pit Vipers as warded Vipers just seemed too much value to omit. While they provide a good way to deal with Water's Monsters that are quickly out of range of our other minions, they have little offensive value and don't tangle well with Skeletons.

Added Crusade to further boost minions and get behind defensive sites. There's a pretty even split on Earth and Fire minions so this seemed to make sense, though being uniques I did not get to test them enough.

Added Ring of Morrigan and 2 Torshammar trinkets. It feels strange to leave home without a Ring but I can see that it may be too much of a liability with the amount of Swap going around. Trinkets seem important to close the gap between our many warded 3 power minions and Water's bigger stuff.

Cuts are some Magics and Kettletop Leprechaun as they feel terrible as topdecks and are not very offensive but the value is definitely there and I can be convinced otherwise.

Testing and Cornerstone:

Went 3-1 at our 16 player cornerstone, narrowly missing top 4. The loss was against Mist Necromancer while wins were against less meta builds (2 Sorcerer, 1 Dust Necromancer) while mostly being on the play which gives the deck a big boost.

In other testing I am not convinced that the deck can hold its ground against prevailing Necro builds but I also need much more experience with the deck before giving any final verdict.
