From what we've seen so far I've liked
Liliana, Death's Majesty,
Channeler Initiate,
Soul-Scar Mage,
Combat Celebrant,
Mouth // Feed and
Crocodile of the Crossing. I like
Cast Out for the peasant list I'm working on too. I hope that we get some good embalm creatures. the ones we've seen are neat but very ho-hum. I hate working on cubes during spoiler season because there's so many things that could change from day to day.
I like the new Liliana as support for solar flare type decks. It has some synergies with graveyard themes with the +1 and making one token for 5 mana doesn't seem too obnoxious. Obviously it can spiral out of control but I'm hopeful.
Crocodile of the Crossing is another card that I like as support for a "Fires" type G/R midrange deck. The haste is nice and at worst it has the same stats as
Vengevine. It seems really neat with things like
Gravecrawler and
Bloodghast. You could even throw the counter on a
Wall of Blossoms or grow a
Strangleroot Geist.
Combat Celebrant seems like a neat card with a unique but powerful effect. I like that it adds redundancy to Kiki-Twin combo family as well as being pretty fragile. The card feels good with
Lightning Mauler and causes
Surrak, the Hunt Caller to trigger which I like.
Mouth // Feed is a really wonky card that feels like
Call of the Herd and
Harmonize were mashed together but I really like it. My only concern is, how often are there going to be board states where you want the extra token from Call of the Herd and how often will you have Feed in the graveyard after a boardwipe wishing you could make another token or just draw 3 cards. I have high hopes for this one but some concerns too. more stuff to cast out of the graveyard is always welcome.
Soul-Scar Mage is neat since it's an aggressive one drop with prowess so it helps those decks out. The wither text that it has is going to satisfy my obsession with
Puncture Blast so I won't have to jam that into my higher power list. I'm curious how this works with Volta Charge. I'm pretty sure it would put 4 counters on a creature once that's all said and done.
Cast Out seems like a neat card for the peasant list I'm working on. The effect is good and it marries the cycling and enchantments matters themes. I hope the trials and cartouches end up being good enough to play. I really like
Trial of Knowledge as kind of a peasant
Attunement that married
Compulsive Research. You probably won't get to pick it back up but triggering enchantment stuff is nice.
For standard, it's nice that they reprinted an answer for
Scrapheap Scrounger in
Magma Spray.
Scarab Feast seems like it can do neat stuff with shutting down delirium even though that deck is down right now.
EDIT: Insert rant about using Naga over Snakes again.
Liliana, Death's Majesty seems pretty perfect for what my format wants, and I think will take the place of both
Ob Nixilis, Reignited and
Whip of Erebos, which is sweet for multiple reasons, not the least of which is having a free slot to fiddle around with.
...Now what to put into the free slot....
