Hi, so I'm done with the league, done 38 challenges, killed all uber bosses beside exarch (I'm bad at avoiding molten balls, would probably have to change my setup for this fight, I dont care that much), done wave 30 Simulacrum w/o much trouble and wanted to share my build, Trickster SST:

PoB: https://pastebin.com/zpnLvhVt

highlights of the build:
95% evade chance w/o jade flask,
66% damage from spell hits prevented thanks to Tricksters' Spellbreaker + Devouring Diadem,
~18m dmg (could do higher single damage with penetration enchant on boots but I was too lazy to get it),
crazy clear with the SST enchant, 2 pierce and awakened fork,
very tanky - I leveled up to 90% of 98 while delving to depth 500 and running crazy maps with 8 mods and giga juice (died to reflect 2 times and then wanted to do ubers and lost all xp tho, lol)
60%/75% block with Glancing Blows which further reduces spell damage from hits,
elemental ailment immune with Lethe Shade,
fairly cheap beside the Ashes (I was using a rare amulet with +1 and stats to around level 94),
fast.
