Something I have observed is that it has been a very long time since ST has been the tier 1/aka preferred deck of choice to climb ladder since master mirror released.
I remember how people hated Harmony that was on top since it was introduced. But ever since the nerf, not once has any deck from ST been described as tier 1.
I am not saying they haven't had great decks. Precision strike, nature's Gift, elves and even dwarves were all great.
Since master mirror every faction has had at least one deck be Tier 1. SK: Warriors, SY: Pirates Cove, NR: witchers, NG: Meta breaker, MO: Kelly/Viy.
Even after way of the witcher released, it didn't impact as much as people expected.
I guess it is a good thing in a way that ST never had those broken decks, but I feel like it would be awesome to see my favourite faction have one deck be on top (and hopefully not be broken, which most likely will not happen).
