For reference, this is my list. I think Sorceror’s Apprentice is also redundant in this list, since most of your spells will already be discounted by either Leyline Manipulator or Primordial Glyph. And, as seen in my list, I think Igneuous Elemental is better than Amalgam in this list, since getting two 1 mana Elementals can greatly help the Elemental triggering you need for Blazecaller, Servant and Bonfire Elemental.

I am very excited to see where this archtype lands, it seems really solid and it also has outs against cubelock in the form of direct damage and more card advantage, and flexibility in the form of Primordial Glyph. We shall see.

I have been experimenting with a similar list, and I strongly believe Ruby Spellstone is pretty good in a deck like this. You will be playing a vast amount of elementals if things go right, and it even synergises pretty well with Leyline Manipulator. Perhaps instead of Frost Bolt?

I think I’d try and find room for Glass Knight. You have potentially six sources of lifegain.

I think I agree with the above posters. Doomguard is still a very solid card, even without Malchezaar’s Imp, and he’s also great with Gul’Dan. I think I would maybe try and find room for Glinda Crowskin (perhaps instead of Godfrey?) She seems pretty good in this sort of deck; Gettiing 2 Hooked Reavers or Chittering Tunnelers seems pretty good. Maybe find room for Gnomeferatu as well.

Could this be usable in Wild secret paladin as a 1-of? Maybe replacing a Spellbreaker or something?
