First, RRC, I must say I'm happy to see that your support to ST is constant. Keep up the good work fellow Scoiata'el.
As a ST main myself, I clearly find this expansion disappointing. I have no problem with the fact that Harmony archetype was nerfed to the ground. It dominated the meta during 7 months, so it can sit out for a few months right now.
But I would have hoped that the new ST archetype was effective. Unfortunately, not only Symbiosis is uneffective in this meta, but moreover, it is the perfect prey for the strongest decks (Nilfgaard spies and of course Skellige Warriors).
From rank 7 to 3, playing Symbiosis was fun. I mainly fought Wild Hunt decks which were beatable. Then I crossed the way of NG and SK and the fun suddenly disappeared.
I think Symbiosis deserves a topic of its own where to discuss its major flaws. So I won't talk too much about this archetype here.
I would rather talk about the main problem of ST, which is in my opinion rather the same since closed beta : their different archetypes don't work well together.
They are hard to combine for one simple reason : they are mainly racial (Dwarfs, Elves, Dryads/Symbiosis) or the opposite (Harmony).
All the rest (Move, Handbuff) are not fully fleshed out archetypes but sub-archetypes.
Therefore, usually, each new expansion benefits to only one ST archetype (Dwarves, Elves or Dryads). Harmony was an exception because of its very nature ; it could benefit from almost any new cards. But Harmony is now too weak to benefit from anything.
The last two expansions illustrate this problem well. The elf scenario only works in an elf deck. Eithne evolving card only works in a symbiosis deck. Combining these two cards is really complicated.
In the meantime, NG can astonishingly combine its Masquerade ball and Evolving Usurper. Moreover, several of its archetypes (aristocrats, spies, assimilate) work well together.
I think the solution for ST would be to promote its sub-archetypes (Handbuff, Move), so that they combine well with racial or harmony archetypes.
I remember a time when a Handbuff deck with a few Harmony cards was pretty effective (during Crimson Curse). But for the moment, Handbuff is unplayable.
So, that's what I hope for the future of ST, more interactions between its different archetypes / sub-archetypes.
Also, I agree With DRK3 : right now, Elf archetype is the most effective. It appears that with a few tech cards, it can counter almost any top tier/annoying decks.
But this is rather frustrating because I already played this deck during the last 6 months. I wanted to try the new archetype, or at least include some of the new cards in my elf deck.
But with the exception of oneiromancy, I don't see anything of interest.
