I think Sorin, Solemn Visitor has a place in this. Tokens+Everything has lifelink=Win. And the ult is pretty scary too.

Having Brimaz, King of Oreskos and Hero of Bladehold together is pretty redundant so I'd say to keep one of them. Glory of Warfare is interesting so if it works for you then go for it. Captain of the Watch is also pretty interesting. Not sure about it since it's a pretty high CMC. Elspeth, Sun's Champion costs the same but is a lot better and has a higher impact. Sorin, Solemn Visitor could probably be replaced by something better (likely another Elspeth). Legion Loyalist isn't that great in the deck since he's super small and if you're going to focus on a token deck then cards that just get out more stuff would be better than him (something like Young Pyromancer but you don't have many triggers so it probably wouldn't be too good). I'm not so sure about Goblin Rabblemaster either since there aren't really that many goblins. Lastly, if you're going to run Dark Confidant then have either a lot more spells that can protect him (more Lightning Bolt s, Lightning Helix , etc.). Otherwise stuff like Phyrexian Arena , Sign in Blood , and Night's Whisper are better.

I have run Mardu midrange focused on tokens for more than half a year and I think I have some experience with this type of deck.

The very first thing I have noticed here. You have here Dark Confidant . No doubt he is great, but I think that if you run him, you definitely should not have here cards that has CMC as high as 6. The possibility to take 6 from him really sucks. Therefore I suggest you to drop both the Elspeth, Sun's Champion and the Captain of the Watch .

Secondly. I am not sure what I am looking at. Is this supposed to be aggro? If so, it is just so slow. Or is it supposed to be control? If so, then it has basically no strength in the late game and surviving into late game is also not certain. Or is this supposed to be midrange? That type of deck seems to fit the best, but then it is again very weak midrange deck, as you have almost no way here how to protect your guys.

This deck should most probably be midrange. Your main power are tokens and you start producing them on T3 or so (that is the reason why this deck is definitely not an aggro deck). With that in mind, you should think about what you will be doing in the previous two turn. The best possibility is to run hand disruption spells. Thoughtseize , Inquisition of Kozilek and Tidehollow Sculler are very, very strong in a deck like this. You remove almost any threat from their hand and then the game will be much more pleasant.

Also, Lightning Bolt should be a 4-of. It is probably one of the best spells you might have here. Direct damage or spot removal in just one card, now that is strong. The same true is for Lightning Helix . The lifegain is very, very important against quick aggro decks.

Now, what I would remove. One of the removed card would definitely be Akroan Hoplite . This card is weak by itself, you have to have good board position to have use from it and even then it is vulnerable to absolutely any spot removal or can be chump blocked, or traded by any creature with power 2 or greater. It could have been good if it had trample, but as it is now, it is too weak.

Another card like this is Legion Loyalist . You deck isn't fast enough to have big use from him and by the time you have enough creatures to have use from him, you are most probably winning anyway. Again, just by itself, he is quite weak and is relatively good only for attacking.

I am also not sure about Mardu Ascendancy . Most of your creatures on the board will be tokens, thus will have no advantage from the ascendancy. It also has very specific mana cost and is good only when you are attacking. To effectively use it, your deck is too slow.

It also might be worth removing Glory of Warfare .

You may also check out my Mardu midrange deck. I thing you may find here some inspiration:

I see what you mean in the deck being a bit scattered. I've narrowed the deck down with some big changes. Threw in some more board control with more lightning bolts/helixes, some more token production via Raise the Alarm and Young Pyromancer (Despite my love of Mardu Ascendancy, my now thinned out creatures list just makes it impractical). Got rid of Dark Confidant in exchange for Phyrexian Arena, bumped up Elspeth by another 1 (I'm considering getting rid of Sorin, but he is another source of creature removal, namely sacrifice which is harder to avoid, and his +1 for lifelink and +1/+0 to all my tokens is just amazing lifegain potential in conjunction with the life I'm gaining from Helix).

Tell me what you think of the new deck.

No Liliana of the Veil for budget concerns, or another reason?

Mainly budget reasons yes. If I could I would. Not sure what I would drop to put her in though. Would probably take out a Glory of Warfare and put in 1 Liliana.

I think that now it looks better. The fact that you have options how to affect the board is huge. I still think that some hand disruption spells would be good here. It is a way how to control what will be played and what won't. Lastly, you may also consider Night's Whisper as the card draw engine (it has synergy with Young Pyromancer ).

Sign in Blood can be better than Night's Whisper in case you need a crazy two damage clutch win and all the bolts and helixes are gone :V

Sign in Blood is double black and only gives you 1 advantage for 2 life. It can be too expensive, but, 3~4 Dark Confidant s would do it better. They will give you 3 cards for 3 life (your average cmc is 1.89, so in 2 turns he nets you 2 cards for 3.78 life by itself, the third card being a removal your oponent wasted, otherwise he'll give even more advantage).

I'd suggest at least switching to Night's Whisper if not Confidant. At this point finish up the sideboard, I really question if Ankle Shanker is worth it, at 5 mana I'd rather see Batterskull myself, maybe Thundermaw Hellkite . Looks good, I'm curious how Goblin Rabblemaster Preforms.

mainboard card suggestions:

Sorin, Lord of Innistrad or Sorin, Solemn Visitor

Brimaz, King of Oreskos

Liliana of the Veil

sideboard card suggestions:

Leyline of Sanctity

Mirran Crusader

Auriok Champion

Rakdos Charm

Rest in Peace

Stony Silence

Torpor Orb

Wear / Tear

All good suggestions, updated my sideboard with that new list of cards, though I'm not sure about Brimaz, as I feel like Hero of Bladehold performs the same job but also buffs the other tokens I already have.

Rabblemaster is actually fairly useful in this deck, he continually supplies pressure and with intangible virtue out he gives meatier blockers for me everyturn. Him combined with Hero of Bladehold is a brutal token machine. I'm not sure about either Sorin's, I'll have to consider them some more or get a good argument in favor of them. Ankle Shanker was a left over from my original dream of running him as my star player in a swarmy deck, but that fell apart out the front gate. I'd like to keep my cmc low so Dark Confidant doesn't eat me (Like he would with Captain or Elspeth) so Batterskull and Thundermaw are probably no goes.

I would run Brimaz, King of Oreskos over Hero of Bladehold just because of Dark Confidant . You never want to lose 4 life right away so the lower cmc is good and essentially the same job is performed so it seems like a better fit (although, in general, I do think that Brimaz is inferior). The side looks pretty good, although having Rakdos Charm and Rest in Peace seems a bit redundant. The deck seems pretty solid otherwise.

There are few 4 ofs in the maindeck. You said that Goblin Rabblemaster gives you tokens, but you forgot that he's a 2 of and you will very rarely draw him with Intangible Virtue . My tip is, instead of just trowing cool stuff in the deck, choose what is really optimal for your deck, and make it a 4 of.

Aggro is about consistency.

@bigguy99

Brimaz, King of Oreskos , is kind of superior than Hero of Bladehold , not only because of Dark Confidant . The CMC and Vigilance puts it in a better spot for modern in most of situations, because modern is a Midrangish format (Abrupt Decay still a thing, but I don't think that it already makes pros turning into cons).

And about Rakdos Charm and Rest in Peace , is because Charm kills Twin decks, and is still somewhat useful against Affinity. But Rest is important too! Pod is really a deck.
