To start this off, i want to say that im from Sweden so my grammar won't be perfect, with that said, let's begin.
I've had some problems with a consistent MD (been trying Steve Sadin's 9-0 list) but it haven't worked out at all, so after a lot of playtesting (mws, irl, magic online) i've concluded something like this to be my final MD list:
4 Goblin Lackey
4 Goblin Matron
4 Goblin Piledriver
4 Goblin Ringleader
4 Goblin Warchief
2 Siege-Gang Commander
4 Warren Instigator
1 Tin Street Hooligan
3 Warren Weirding
4 Lightning Bolt
4 Aether Vial
3 Badlands
2 Taiga
4 Bloodstained Mire
3 Scalding Tarn
4 Wasteland
6 Mountain
As you can see, the MD do only have wasteland as mana denial, but this deck is so aggressive so the opponent has to answer on every creature i play the first 3 rounds to not die.
The SB is not yet decided, this is all i've come up to so far:
3 Krosan Grip
I want to play Pyrokinesis since i always get happy when i get to draw it against aggro/mirror.
I also want Perish against Zoo, tempo decks and new horizon.
I also want Blood Moon against landstill (also it's OK against Zoo, they can only play their fireblasts and bolts)
I want Chalice of the Void against combo and Zoo.
I want Extirpate/Relic/Crypt against Survival/Graveyard decks
I want Mindbreak Trap or Thron of Amethyst against Combo
Many of those cards fills the same role but i can't decide what to play... The only thing im pretty sure about is that i want to play Mindbreak Trap over Thorn, since pressure + unexpected hate really helps when facing combo.
But i need help to find a consistent SB (Im pretty sure the MD is consistent as it is, but if you have a tip, please share it). I've played the deck for about 2 years and i have placed very consistent on all legacy tournament, exept one. The sideevent at GP Gothenburg, i went 4-4, before that my worst record was 4-2...
In Gothenburg i played Steve Sadins list and i did not like it (but it was good against mirror, faced 3 mirror games, won 2 pretty stable, the one i lost was kinda close).
I would love to hear all your thoughts.
