Yeah, my thoughts exactly - I might even double up on
Herald of the Pantheon and
Eidolon of Blossoms, to make sure this theme is a thing. Abzan seems like the natural place to extend the theme beyond green - white already has lots of
Pacifism and
Oblivion Ring-type cards, while black seems to have the most high impact not-just-enchantments, like
Doomwake Giant and
Whip of Erebos.
Yup. I just built in an enchantress theme into Abzan. It's a perfect fit IMO. Tailor made for that color combination with cards most cubes are already running (requiring minimal fringe card support).
Song of the Dryads BTW is completely insane in this deck.
My 2 cents from testing… I wouldn't try to over support this. You really don't need to. I went full tilt with my first version and if you try and build a deck completely reliant on enchantments, you end up with an inconsistent unplayable pile of jank. Cube isn't constructed and I often forget that.
Eidolon of Blossoms and
Doomwake Giant are both very playable with no other support (in my cube they are… YMMV based on power level). Add in a half dozen enchantments (things you'd play anyway - O-ring, etc), and those two cards sky rocket in value. You honestly don't need anything else in that deck to make it very powerful.
Just today I was testing this very deck and it started with me curving with aggressive threats (completely unrelated to enchantress). I over extended into a Damnation, but an Eidolon of Blossoms and two enchantments later, and I won the game anyway. If that aggressive two drop I had
argothian enchantress instead, I would have not won that game. No early pressure means my opponents holds damnation longer and I lose everything with no way to recover.
Not suggesting that Herald of the Panteon isn't a great fit (or that it wouldn't help with an aggressive start). But he's more "all-in" on the theme. What happens when you only have a handful of enchantments? He's just a bear on his own. Is that worth playing over something that does more for you now just so you can make Eidolon better later? Maybe and maybe not. I'm not sure I'm feeling that honestly.
These types of things may also be group dependent. How focused are your builds? If you draft with 8 people, maybe you guys wind up with more consistent and focused builds than our group does. But that isn't how drafts tend to go here. Here you build a deck with synergies, but in a best out of three match it is rare (in my experience anyway) when you win the game the same way twice even if you made a focused deck (unless it's ultra generic like TurnDudesSideways.dec). So I personally have moved away from over focusing on single win conditions.
Again, I'm not necessarily saying Herald is too single minded. He may not be and I'm going to test him in this deck too. But it's worth keeping in mind that it's easy to see all this compatibility between pieces and then forget that unless you are going to run multiple copies, you won't be drawing them more than once every couple games. And even with multiple copies, can you grab them all?
Sorry, rambling a bit there. But hope it's helpful. I've specifically been working on adding this archetype and just wanted to share my own evolution of thought on it. I think you can over support it and wind up with something less viable in the process. Cheers.
