[DTB] Vial Goblins

[GreenOne]

I have been testing Warren Weirding (-1 Gem Palm, -1 Piledriver, -1 Mogg F. I run 2 Wort and 1 Siege Gang.

I'd never cut Piledriver or Fanatics for Weirding as it doesn't fill the same role. Weirding is IMO a substitute/addition to Gempalms, that took the creature removal slots in the last years. Piledriver is sort of "finisher" in the deck and Fanatic is general utility (against grave-based combo decks, fish decks, Jitte, etc)
As I suggested a couple of pages ago, I'd play that list:

// Lands
4 [TE] Wasteland
4 [b] Badlands
4 [ON] Wooded Foothills
3 [7E] Mountain (1)
4 [ON] Bloodstained Mire
1 [P3] Swamp (2)
2 [MM] Rishadan Port

// Creatures
4 [7E] Goblin Matron
4 [AP] Goblin Ringleader
1 [LE] Gempalm Incinerator
4 [ON] Goblin Piledriver
4 [SC] Goblin Warchief
1 [SC] Siege-Gang Commander
4 [US] Goblin Lackey
2 [LRW] Wort, Boggart Auntie
4 [10E] Mogg Fanatic

// Spells
4 [DS] AEther Vial
4 [MOR] Warren Weirding

Note that the list is 58 cards so you can add 2 goblins of choice depending on meta (Goblin tinkerer, Sharpshooter, more Gempalms, Mad Auntie...), but I see no reason to cut Fanatics, Piledrivers and Matrons (especially Matrons from the deck)

After testing, I came to the following conclusions:

1) Put in a basic swamp.

Wasteland kept me of Warren Weirding a number of times. Vial and Lacky obviously don't fix mana for Warren Weirding, and this change had a notable effect. I cut a port for it, so as to not effect my red count.

I'm with you on this, I didn't find port that effective anymore in this meta. I'm down to 2 at the moment, but maybe I'll cut one or both in the future, depending on cards I decide to run and meta.

2) I'm thinking of cutting a matron for the 4th Warren Weirding.

I was tutoring for it so frequently, this seems like the right move, but I would rather test against decks where Warren Weirding is weaker before making that sort of move.

Don't do it. Matron is the Demonic Tutor of the deck, it allows shenanigans with warchief and Piledriver, tutors for Removal against aggro-control, but it's great too vs control, where it's part of your card advantage machine (tutors for Ringleader/Wort).

What results did you put up in youre testing? Bad thing Weirdings sucks hard in the mirror, but I can see the aggro-control matchup much become a lot better.
