There was a Brazilian open tourney with 108 entrants today, I think there was a rule in place that you had to play reasonably new decks so obviously take these results with a MASSIVE grain of salt. But this might give some ideas for which of the new archetypes might end up panning out. Here's a breakdown of the decks that made top cut:
Draven Sion Discard Midrange 6 (CEBQCAIDCQCACBABEYTS2BYFAMAQGBAFAYEQ2AQBAMCBEAIEAQIAA)

The winner was Iannogueria running Fizz Nami Go Fish, Discard midrange, and 3 Senna, 2 TF, 1 Elise Go Hard. SadCowboy got 2nd with Discard Midrange, Cait Teemo Foundry, and Akshan Sivir BC. Again, MASSIVE grain of salt with these results as they are taking place in an unfocused and largely open meta. Good players can potentially carry medicore decks to success in the short-term especially when everyone else is also likely running mediocre lists. Also completely absent was any previously established decks, so it's hard to know how these decks match up vs the previously established meta from these results.
The biggest deck by a landslide was Discard Midrange, while the deck was a pretty obvious one and was probably pretty common, it does seem like it wasn't holding the players back at least and it did fairly well overall. 5 total Nami decks showed up too, 3 with P&Z Fizz, 1 with BC Fizz, and 1 BC without Fizz. While Nami is definitely vulnerable to removal, at the very least she is pretty powerful when on board with a handful of spells and some Elusives to put the buffs on. At the very least the deck might be a bit more vulnerable to removal than other Elusive spam decks because there's no protective spells or Spell Shield. There were quite a few Senna decks too, the Go Hard version that won seems pretty promising, but none that were able to combine her effectively with Veigar.
