try vedalken entrancer and the crab. also where is the haunting echoes in the deck? mill has to have answers for the graveyard. more effective of a card might be something that can untap your creatures so you can use their effects again. also you have no draw advantage and any mill deck will run out of speed by turn 4 or 5. you need some way to replenish your hand. also you might want to figure out how to put in counterspells.

I think you should just pull out all the white. since your not running a selensye type build its no point to splash white in for 8 cards 4 of which are dual colored. also i think you can pull out 1 or 2 gravepacts. its a bit harsh on your curve and i think 4's a bit excessive since you can mass the field that fast. doubling and the ancient are powerful in this deck but another suggestion is using paradox haze for multiple upkeeps. that way you can make the most out of sporesower and the sporoloth ancient. it also gives you a semi control element which im sure is needed if case be that you're going up against board wipes and other decks that can respond very fast. fetch lands and pain lands might be useful to you too in the deck since it will help with the mana accel.

I would consider liliana and sorin for this deck and if you are look for a way to get rid of cards possibly use duress and combo with either megrim or sanguine bond so they take a good burning from your life gain.

no other mills other than crab? i dont think this deck can call itself a mill deck. Also no answers to creatures or answers to flyers? this deck would die very fast. frost cant hold out like denial. also of all cards memory erosion? its only good for multiplayer. in solo matches its way too slow. If this deck were to go up against a good standard mill it wont last. if it were to end up against an extended my turn 5 or so i can probably finish the game with glimpse the unthinkable. if you are considering mill cards theres plenty of choices other than crab's landfall.

Pull out nemesis and use wall of denial if you wanna splash white. If you want to use bloodchief ascension then splash red. I do not see jace in this deck either. Jace is a staple in any mill deck. Duress should be sideboard as well as snare. Main deck blade or try hideous end. If you splash red then burst lighting and lightning bolt and if splash white then oblivion ring and path to exile as well as journey to nowhere. you might also want to consider counter spells such as countersquall or some method for you to draw out your hand. Land wise you should be using terramorphic with hedron to mill for 6 or more. That and you have to use dual lands. Although basic lands are good there isnt much against nonbasic so you should use it. as for any mill deck, it doesnt work against red deck wins, white weenies, or jund aggro much. that about it for the deck. Its a solid build but you need answers to stuff such as chandra ablaze and other cards.

This deck is beatable... all anyone has to do is unsideboard their sadistic sacrament. In the event that colossus is summoned all one needs is an unsummon..... mono-green is not the way to go especially in today's meta with so much removal and exiling cards. as for the slivers, it takes skill to build a sliver deck. anyone can throw random cards together but not everyone can make a deck that is able to utilize all cards available in that deck to make it hard to beat.

Ok since ive read dpopinski's comment and scottojr's about the deck wanting to run a black card and white deck, I suggest a draw dmg or draw mill deck. Which ever seems more likable. Im assuming you want to use spiteful visions to its fullest extent. if case be that then the deck will be extended and not standard legal. As for color choice, since spiteful is either black or red and you want to use jani (planeswalker pet name) then id say go black with a splash of white. Cards you might be interested in are font of mythos, howling mines, silence, more oblivion rings, possibly elspeth, doomblades, corrupt, pestilence, tendrils of corruption, pacifisms, day of judgements/wrath of gods, damnation, or some of the newer allies from zendikar. If you are interested in older cards, akroma, dark rituals, thrulls, maybe enemy colored cards from ravnical block, or something possibly from time spiral or onslaught. Torment was a nice set for black but i dont think it would fit with your theme.

I suggest wall of denial for the deck. These small guys wont hold up against spot removal, fallout, or in fact any spell aimed at them. You might want want to look into the refuges for late game small life gains as well as traumatize. Although the build is effective its lacking in major dmg reduction and with traumatize you can take out half of their deck making all your other mills more worth while. You also might want to consider jace in the deck. I personally run a standard mill thats similar to this build and you will top deck really fast if you dont run something that helps you draw. Also using jace works both in thinning out the opponent's deck and helping you maintain a hand.

If you can add in chandra ablaze or chandra nalaar.

theres better burns and if you are using a burn deck stick with red/black instead of using blue. Mill and burn arent worth it together. Also if you wanna run a deck that burns in standard really well you'd need to use chandra ablaze. You can try sorin markov/chandra ablaze deck deck build if you want. It would encompass cards like terminate, blightning, megrim possibly, lightning bolt, pyromancer's ascension, bloodchief ascension, and some more recent burn spells.

It really depends on what colors you are running. If you can tell me what colors you want to run i can probably find some way to help you figure out a deck. Also 1 copy of each dragon isnt that ideal you'd want more copies.

It seems pretty good in the test run since everything is low mana costing. The only thing i wanna change is add in Sorin Markov for his abilities.

any decently built sliver deck will easily trump this deck. You can destroy targets all i need is a pulmonic and anything you destroy will go to the top of my deck. That or i can just cast a ward and go pro black. Ill gladly pay 5 life to use it. As other people have said crystalline is good but i personally think its overrated. As for exhausting the hand really fast thats why you combo shifting and synapse sliver to replenish your hand. If you add an ice cave in a 5 colored deck you can just counter everything thats cast or necrotic everything that comes into play and combo it with pulmonic to never have a sliver die. So in all cases this deck isnt that effect especially if someone is running a sliver overlord and just sacs the plague. My 2 cents on this deck.

Pull out your artifacts and plated slivers. get 4 copies of gemhide, 2-3 copies of crypt. Pull out the frenzy and talons for a sedge, and pull out all 3 winged for pulmonic. add in akroma's memorial and mirari's wake to produce more lands. you wont need the spells either with that. Put more dual mana lands or fetch lands in to generate a decent mana pool. you dont need that much 18 or so should be enough. Sideboard your sidewinder and screeching for other cards like might or bonesplitter sliver for more dmg. Add in a shifting as well. In my personal opinion crystaline is overrated but its your choice if you want to add it in or not. You can check my deck for more ideas.

Personally i feel that millstone is too slow. If you were to use white you might as well work with path to exile and then combo it with the zendikar card, archive trap to mill for free. Besides that, pull out the fonts. They arent useful in your deck without cards like underworld dreams to deal dmg. as for your mana base, it'd be wise to use some basic lands because anything that targets non basic lands will screw you over. the cane should be sideboarded so you have more space to put useful spells like traumatize and glimpse in since its extended. Consider using also, haunting echoes and the zendikar card sadistic sacrament for additional milling capabilities. I personally prefer some creatures in the deck so a weenie deck wont be able to over run you and red deck wins will have a harder time doing you in.

Id say pull out the metallic slivers and add akroma's memorial into the deck. that way you dont need to waste spaces for certain slivers. Also replace both darkhearts with shifting. The deck will be able to get the game finished in no time like that. I would also suggest sideboarding toxin and magma. In their place add might slivers for more power and addition ward slivers. If you play memorial you only need 3 ward slivers to have protection from all colors. Other than those minor pulls this deck is pretty good. You can check mine for ideas.

the mana is just right. Boros signets can accelerate the mana and garrison produces 2 for 1 land. Most of my spells and creatures are pretty low in cost and with liege on the field i can easily burn for alot more than what i pay for. for example with bolts i can do 6 dmg and with helix i can gain 6 and do 6. In anycase theres 8 ways to stop a good number of creatures from doing dmg to me not to mention late game enders. this deck should be standard legal if im not mistaken. Planechase cards should be standard.

Keep it at 60 cards. Your spells dont seem to help as much so id say just scrap them. Wild pair, Akroma's memorial, cryptic gateway, those will get your slivers cranking out fast. Slivers wise put some in your sideboard and some in your main. Often times most people dont play enchantments so harmonic is not a great main. Also keep your slivers at a 2 to 4 copies to make sure you actually draw them. You can take a look at my sliver deck to get ideas.

This is my standard burn lifegain deck. Concept is to just stall until balefire comes out then combo red with its effect to burn for more and combo white to gain some life in the process. With the sideboard it can become a beatstick deck that can burn as well.
