Notes & Combos
I do not advise adding pixies or gamma burst. These two were very, very niche choices that basically never came up and had only theoretical value. Would recommend instead using either an additional copy of Kisikil and imperm, or 2 more copies of imperm.
Without scythe, the basic good endboard should be either IP/Elf/Both twins OR Carrot/Red/Elf/Both twins backed by handtraps/backrow (ie a searched smashers)
