I hit S-rank a few days ago and just wanted to share the deck lists I have used this season. Most of them are unconventional.
Artifact Aggro Sajj
An aggressive artifact variant that aims to close games early by going
face. The game can also stall into late game by building up the combo
pieces for a satisfying time maelstrom finish.
This is the deck that I have used from Rank reset until Diamond combined
with some other Sajj variants such as Dying Wish Sajj, Oserix Sajj. But
this is the Sajj list that I use most of the time.
Wish Zirix
The deck aims to complete all the 3 wishes in order to drop off Pantherans for free.
Along with Aymara Healers, your opponent would need to have very good
removals if they want to survive the next turn. Third wish is the MVP of
this deck as it allows my dervishes to hit face when the opponent least
expects it. Whisper of the sands is another special mention as it
closes the game easily especially on Songhai match-ups because they do
not seem to care about my obelysks. This is the deck list that I have
used from Diamond 5 - Diamond 1. It was very close to getting me to rank
S 2 chevrons off then onto a losing streak so I used the next deck.
Shadow Creep
This is my go to deck if I wanted to climb. When I had my losing streak, I used this
deck to boost my morale to climb back up. It has a very clear win
condition and probably my most consistent deck. Not really
unconventional but I included it here because this is the deck I have
used from Diamond 1 to S.
Wall Faie
This is the current deck I am using at S-rank went from rank 20 to rank 60 because
of this. I tried a lot of variations and still cannot get the perfect
combination to stabilize the deck. Warning: Do not ever
try to play this wall list if you get easily tilted. One Skorn will
throw your win condition down the drain. Still a very fun deck and I
plan to optimize this further even if it puts me at the bottom of S lol.
