Overall some solid improvements! Might I suggest a few more? In my experience Sorin, Solemn Visitor or Sorin, Lord of Innistrad are the ideal planeswalkers for an orzhov tokens deck. Both are the same cmc and both help to boost your tokens or if need be they can spit out tokens as well. Secondly, if you have the money, Auriok Champion is just so much better than Soul Warden. Main boarding it means you are able to beat twin in most game 1's as they can not combo off with their exarchs. Not to mention it serves as a great blocker. Next, you can never have too many Intangible Virtue's. Any token deck should be running no less than 4 of those. Speaking of tokens, Hero of Bladehold is a solid addition to token decks. If you manage to attack with her two times the opponent is normally dead. Anyways, just my views, hope this helps!

Firstly, Caves of Koilos is strictly better than City of Brass in this deck, since you can tap for colorless without taking damage.

In my experience, 6-7 discard spells is enough, you don't need two playsets. In fact, a t1 deck (Junk) usually plays 5-6. I'd drop one of each Thoughtseize and Inquisition of Kozilek.

Pack Rat really isn't very good in Modern. I've tested it, and it never really works to be honest. What's really good is a 3rd Brimaz! =D

You need 4x Raise the Alarm, as it's your best way to swing the tempo in your favor vs. control. (aka, end step Raise -- they counter it and you cast a threat during your turn, or they don't and you commence the beats.)

4x Spectral Procession, always. It's your best threat -- it's always a 3-1 if you can slip it in under a counter.

Really consider Zealous Persecution. It's a VERY good card, allowing swings for lethal, blowing out the mirror match, blanking Twin combo for a turn, making your guys trump Burn's, sweeping away Young Pyromancer and Master of Waves tokens, pressuring control, 1-for-1-ing Junk's Lingering Souls, etc., etc. I love this card.

Rest in Peace is techy sideboard tech. Stony Silence > Kataki, War's Wage. Dismember would be good sideboard for Twin and Goyf decks, as well as manlands (mainly Celestial Colonnade. Runed Halo naming Deceiver Exarch, or Primeval Titan, or Siege Rhino, or Boros Charm, etc., etc., is always very good.

Also, linking the Tokens expect here on tappedout: xzzane

Sorry for the triple post, but I forgot that I actually have my list here on tappedout. If you want to look at it, here it is:

Much of what TheAnnihilator said is correct. Something to note is that Zealous Persecution has actually lost a lot of its usefulness. Dismember is better now due to the various high toughness creatures that are common now. I'm currently on my phone in Virginia trying to find a bus (not my native state), so I'll give a more in depth explanation of how to improve this later.

Ok, so to go further in depth on the ZP thing, a lot of decks nowadays don't run that many 1 toughness creatures, and most of the threats have evolved to higher cmc creatures, with greater toughness. Tasigur, the Golden Fang, Siege Rhino, etc. So that's why a few ZP can be cut for Dismember. I still run 1 ZP though, because it is great for certain situations like Annihilator said. Take out all of your creatures; there are much better spots for all of them. Take a look at Swarm and Conquer V 2.0 for a non budget list and B/W Token Budget for a budget list that I've made. Any questions?

Thanks for the input guys, I'm kind of toying with Tasigur and maybe a slightly more mid-range of center feel at the moment. The double blue splash is only for his ability and im debating going double green instead with black/green and white/green fetches for more interesting sideboard options.

suggestions?

Don't take this the wrong way, but I don't think Tasigur fits here. The idea of the deck is to out-resource your opponent by wasting their spot removal (aka, make a bunch of tokens, or play creatures that generate more creatures). I could see using something like Voice of Resurgence or Kitchen Finks to be more midrangey or otherwise creature-heavy, but Tasigur is really about virtual card advantage, not pure card advantage like token generators. Therefore, he's very good in a control deck that looks to gain virtual advantage, but not so good in a direct advantage plan.

Something like Brimaz is different, because he provides direct, on-the-field, non-mana requiring advantage. Tasigur just... doesn't. Tasigur's ability for this deck is a hindrance, messes up the mostly harmless manabase with limited returns, and also costs too much mana to be very useful -- what cards do you have that control what's in your graveyard? In addition, Tasigur fits a much more grindy, slower-paced game... not what tokens is looking to do.

tl;dr: Tasigur is too slow, doesn't fit the game-plan, messes with the manabase too much, and doesn't always get relevant cards anyways.

What about the blue splash for Narset Transcendent / maybe some cantrips like Serum Visions or Gitaxian Probe instead of adding tasigur? I think narset would be pretty powerful here because she could rebound pretty much everything in this deck. Spectral Procession? How about Spectral Procession x2 for the price of 1. Not to mention, she is realistically a card draw engine at worst. Anyways, just an idea let me know what you think.

Oh and narset would be more mana efficient because she doesnt need 2 blue to be useful like tasigur.

Annihilator is correct. Do not add Tasigur. I honestly advise against Brimaz as well though. And I also advise against splashing blue.

Yeah I understand where you guys are coming from, I figured you could delve cast tasigur to control what was in the graveyard then get more use out of the token generators but it is quite a stretch lol.

I'll change over to marsh flats when I get a playset but this I think I'm more comfortable with. Brimaz is staying because in the meta im playing in currently, no one really has solid answers to him and he is just a really really nice token generator.

If no one runs removal then why not play Hero of Bladehold?

Why so much hate on brimaz? my reasoning would be vigilance tokens and 1 less cmc to get him out.

I can't speak for xzzane but as far as I see it Hero of Bladehold swings twice and your opponent is probably dead. While on the other hand brimaz takes awhile to do stuff, even then hero spits out more tokens and has a board wide benefit for your team.

Turn 3 you want to stabilize. Playing a Spectral Procession does that better than Brimaz does. Then you can curve into a hero for much more firepower than Brimaz.

Have you done any deck tech/strategy videos for B/W Tokens?

I'd be very interested in picking your brain as I'm fairly new to the game (only one year so far).

I'm supposed to write an in depth b/w token primer for ages, but I tend to be a world class procrastinator haha. It'll get done soon though. As for videos I have no clue how to go about doing that. It would be a cool idea though.

Wing Shards is in sideboard as two regular players are currently using G/W bogles in my local meta.

Chalice of the Void or Engineered Explosives are also good options.

Chalice will probably replace it, but it's going to be down the road when I find a playset I can trade for, shards is just so cheap and I love storm with so many instants/sorcerys in this deck.

The only deck that really just destroyed me, (turn 3 loss consistently) was U/G unblockable infect.

Any suggestions against that? His suggestion was surgical extraction after thoughtseize to pull his +4/+4 instants or artful dodges but I'm hoping there's something slightly more reliable?

Chalice of the Void or Engineered Explosives are also good options. Adding 2 Dismember to the main board would also help. Take out an auriok and your sword.

My phone was being weird. Don't side in explosives against infect. It copied the first sentence of my last message.

yeah haha ok. I figured that was what you were saying.
