This decklist is a masterpiece, inspired by the Dadaists
The 1 burnout SB is an incredible piece of tech for this Chalice deck, ray of revelation is super nice as well with gifts. The 2x mystic retrieval is super nice with gifts again, as well as with chart a course. The planeswalker suite is super cool as well, allows for some crazy gifts piles, and each does something unique and different.
Arlinn/Sarkhan/Xenagos all add a ton of pressure and kill opposing walkers super well. Sarkhan in particular is hilarious anti blightsteel tech.
As for the creatures lotus cobra is really nice to pair with the walkers for quick pressure, SFGM adds lifelink crucially and with all the mana in the deck builds in some infinite combos with time walk. Taigam is a cool choice as well, seems absurd alongside Mystic Retrieval, to say nothing of ancestral/merchant scroll/delve spells.
Other cool value choices like Search and Sylvan Library are pretty standard at this point, but notice the BK Spyglass wedged in there as a catchall answer.
In general the deck is super super well built to be able to function under Chalice 1 in general.
Anyway, the list was way way too cool not to post.
