Ichorid & co are in addition to Creeping chill. I think that 4 bloodghast is not enough for hasted creatures, and I added the classic minions (ichorid and ghouls were played long long time ago...)
My list was:
3 null rod
4 creeping chill
Side, I used fow, mistep, chain of vapor and mindbreak, but it's very bad. I didn't like it
This first version got 3-2 (4-1 if I didn't make so big mistakes in one g3). And I'm sure It could be improveda lot.
I played barbarian ring in MKM Rome 2015, several months before the first list using It was publicated.
It's true that a person could use some tech that nobody use before, and they are never considered as the first user due to their list was never publicated.
I had a lot of discussions with my friends regarding these two cards.
All of them agreed that darkblast is bad, and I should play a golgari thug instead. But I like having a card preboard against Jailer, though It is not the most played card now.
Loam is played as Cage or priest 'antihate'. With only those cards, my idea was return lands and play trolls.
Actually, both cards seré irrelevant, as many of the cards, because my opponent or I died before.
To complete this information, my pairings were 1 mirror, 1 blue with vault/key, 3 MUD (2 win 1 Lost), 1 oath. I don't remember the other one.
I lost against fantasy paradoxical un top8, maybe my worst pairing un whole top.
