Allright, so here's the "how the fk does it work?" part.
The deck is a prett slow one that takes some time before it really activates, so several cards both in the main deck and side board are there to mitigate the pressure that we might suffer from early plays. Lightning Bolt, Fire / Ice and Arboreal Grazer fills these slots in the main deck.
What the deck wants to do is generally to discard lands with cardname:Seismic Assault to deal damage to the enemy, then use cards such as Wrenn and Six, Life from the Loam and Slogurk, the Overslime to recur those lands to your hand again.
Trade Routes is used for 3 reasons. The first is pretty straight forwards, use your land cards in hand to generate new cards. Second use is to be able to play your channel lands early in the game to give mana while being able to pick them up later in the game to use their channel effect. And the third one is to make Slogurk, the Overslime to grow rapidly. If you discard a land and opt to dredge a Life from the Loam, Slogurk, the Overslime can grow anywhere between 1 to 4 +1/+1 counters for a single mana, ontop of digging for utility lands that you can return later.
Sadly I have not had a lot of time playtesting it, and I think that the sideboard needs a lot of work. First and foremost I feel like I have doubled down a bit too hard on artifact hate, albeit with a lot of cards with multi purpose.
Anyways, the rundown of why I included the cards are as follows:
Pithing Needle and Relic of Progenitus dont need explaining.
Brotherhood's End was included to deal with asmo decks, affinity, prison tron, goblins, merfolk and other similar decks to these.
Haywire Mite is included to stop Kaldra Compleat, but will probably see play in the same games that my other artifact and enchantment hate cards.
Otawara, Soaring City is just so that you are more likely to draw them, especially in matchups where they run Pithing Needle to stop Boseiju, Who Endures, but is also really good for returning combo pieces to hand, or just big beaters like Murktide Regent. Its also really good vs tokens.
Boseiju, Who Endures just a really solid card, deals with most problems the deck faces, such as graveyard hate and blood moon effects.
Bojuka Bog is a fantastic card in this deck. With this card and Trade Routes you can exile your opponents graveyard every turn if you'd like, although it is only in sorcery speed.
Flusterstorm is there to stop combo decks and decks like neobrand, cascade decks and other similar decks that rely on getting things out quickly.
Orvar, the All-Form is against decks that run Archon of Cruelty or Liliana of the Veil, or other discard effects for that matter.
Cards that I would like to experiment with: Expressive Iteration is a card that I am gonna experiment with in place of Fire / Ice. I think that Fire / Ice is much better at stalling out the game, but expressive is such a valuable card to have in the mid game.
Academy Ruins and Buried Ruin to be able to get artifacts back from the graveyard.
Shadowspear to deal with agressive matchups where the opponent have no good way of dealing with my constructs or Slogurk, the Overslime.
I hope you enjoyed the read, give me some thoughts in the comments if you have any =)
