Here is my rendition of the B/W Weenie deck. The deck is geared toward going wide and overpowering the opponent with lifegain, efficiently costed creatures and removal. Let me know what you think and if there is anything I could do to improve it.
Breakdown
Vicious Conquistador is a solid 1 drop in the deck due to it's guaranteed chip damage essentially making it a 2/2 when on the offense, which this is geared toward.
Legion's Landing is something that you always want to see in your opening hand. It's super easy to flip since the curve is very low and it hits the 1-2-3 curve very easily. Once you gain the ability to create tokens, it's very easy to gain 3-6 life as the game goes on with just the 1/1's, not to mention if you have a banner or a mimic out.
Supernatural Stamina is one of the most underrated and useful Instant cards available in the format IMO. I put it on the same tier as Blossoming Defense. This can be a very useful combat trick, or it can counter targeted removal. It can save your Mimic, Keep Mavren Fein on the battlefield, or it can allow your Gifted Aetherborn to not only trade with a more dangerous creature, but also stay on the field when it would die otherwise.
Bishop's Soldier is the early game life linker that will get us 4-6 life per creature. The main purpose of this creature is to pad our life total and eventually trade it away against a bigger threat.
Gifted Aetherborn is the 2 drop that arguably has the most impact in the deck. It eats 2/2's, trades with near anything, gains you life, and most importantly; it deters attacks as no one wants to lose their Carnage Tyrant or Bristling Hydra to the 2 drop 2/3.
Metallic Mimic while GA has the most single card impact, Metallic Mimic has the greatest impact across the board as it allows more profitable attacks. It turns our tokens from Mavren and Adonto into 2/2's, basically Bishop Soldiers, and puts our GA's above most targeted removal. It turns Vona into a 5/5 and Sanctum Seeker into a much more versitile 4/5.
Arguel's Blood Fast provides the reach that most creature based decks like this lack; lasting card advantage. 13 of our 23 creatures have a lifegain feature built in, this is in addition to the tokens from Fein and Adanto. Arguel's gives us a place to put excess life as well as pushing card advantage. Plus if we flip it, we are able to sac the tokens we create to slowly climb back in the game.
Walk the Plank is the best piece of removal in the deck. It hits everything except Merfolk, which we have other ways to deal with them, chiefly Dusk as it hits everything with a counter from them.
Mavren Fein, Dusk Apostle is the chief token generator of the deck and allows easier chump blocking and life gain. Additionally, the synergies he has with Metallic Mimic and Vanquisher's Banner allow for more efficient use of the tokens. He is also a prime target for Supernatural Stamina as it provides either a Blossoming Defense-esque defense against targeted removal and also a surprise trade as it is rarely seen in standard.
Skymarch Bloodletter is a solid 3 drop, 2/2 flyer that drains when it enters. This is good for getting some early damage and it great when you combined with mark of the vampire; 4/4 lifelink flyer. Additionally, it's ETB will trigger again is it dies with Stamina on it.
Yahenni, Undying Partisan is something that I am playing with. I'm unsure if he fits in this deck. he has the potential to be big when combining mimic/banner and removal spells we have, but I'm not sold on him yet. Will require more testing.
Sanctum Seeker is the main source of damage due to his attack trigger and the fact that he is often a 4/5 or a 5/6 with the mimic and banner combo. The drain is very effective and allows free use of Arguel's since most of the attacking creatures have lifelink as well.
Ixalan's Binding is the best source of indestructible removal. I like it more than Vraska's Contempt for 1 reason, the secondary function of the card. Hit a Hazoret, and all of them become wasted. Hit something like Rampaging Ferocidon and you'd have to worry about it coming down again. Plus it's 3C+W vs 2C+BB
Dusk / Dawn Dusk is essentially the perfect board wipe for Ixalan Vamps. It kills all the larger threats and Dawn can bring back everything except Seeker and Vona. This is basically the panic button.
Vanquisher's Banner is in the deck for it's anthem effect. The +1/+1 is excellent for the tokens and allows our lower curve creatures to trade up more readily. The additional card draw is a plus and compounds with Arguel's nicely.
Vona, Butcher of Magan
is the nail in the coffin for the deck. 4/4, but possibly a 5/5 or 6/6 vigilance lifelinker. She is good on her own, but her activated ability allows us to clear that 1 threat off the board that it stopping our attack. She breaks a stalemate very easily and swings life back in your favor very quickly.
Sideboard
Decommission is the white Appetite for the Unnatural. It's good against control and vehicle decks, there for when you need it.
Duress is good against control decks. It's there to pick out removal and counterspells.
Essence Extraction is there for the heavy creature decks. Good against larger creatures and excellent against aggro.
Grind / Dust is again for the larger creatures matchup. It's an additional step against indestructible creatures.
Mark of the Vampire is there as an additional source of Damage and life gain. This allows a skymarcher to take over games as well as a seeker to become ridiculously powerful.
