What good combinations ST has? ST has the same deck it has been having for more than 6 months. Symbiosis is the only viable deck and that falls flat against any SK and SY decks. The same Symbiosis with one or two cards changed for the top end gold. This is the only thing ST has ever had in sooooo long. Yes, it had GT for one month. If any ST deck gets as good as the SK decks, it gets nerfed to death.
Lets not pretend that ST has many combinations. Symbiosis with Oak, Symbiosis without Oak, Symbiosis with Etrial+Maruga, Symbiosis without Etrial+Maruga, Symbiosis with Shaping Nature, Symbiosis without Shaping Nature. This is not "good combinations" at all.
Once in a while someone pissed with all the greedy non-sense that is happening might go for no unit PS or Traps PS and quickly realise that no amount of control is good enough to control all the greed happening and then switch back to Symbiosis or some other factions. The big revamp ST had was couple of bronzes on Handbuff which was played for 2 weeks and then vanished.
Who wants to bet that CDPR will buff Warriors to be playable and competitive before they touch any ST dead archetypes like Elves, Dwarfs, or Harmony? SK had Alchemy, Rain, and Pirates and yet the have got the 4th deck playable with Self-Wound. Meanwhile ST has been playing Symbiosis for many many months. Next patch surely MO will get Wild Hunt or Vampire buffs and ST will get couple of dead cards playable without touching the archetype they are supposed to help.
