See the last blog post for full reasoning of offering -> sigil. TL;DR: Liked the modality, liked more lifegain in black. Both provide sacrifice synergy, playing nicely for red goblins and white recursion.

After considering, Infiltrator Il-Kor was often overlooked for other, more reliable lategame win conditions. I'm looking for other early survival options for blue- current thought is Reef Shaman, which comes with the bonus fixing option, plus possible color lockout on opponents. Sage of Epityr is a close runner-up, but I hesitate to give blue early win conditions outside of combat tricks. The Unsubstantiate on two mana is enough unconditional early removal, I think.

I'm considering Green's role right now, and while I'm not updating at the moment, I'm considering swapping Wall of Vines for Jaddi Offshoot, and Snakeskin Veil for Sudden Spinnerets. If I choose to remove Feldon's Cane, the graveyard shuffle will end up in green, probably via Blessed Respite. This is all highly theoretical at the moment- especially removing one of my favorites in Feldon's Cane- but I'm trying to listen to broader feedback as I continue to refine the list.
