given that you're running slivers. in green. I suggest using Into the Wilds in place of Darksteel Ingot . also I STRONGLY suggest you run a PLAYSET of Boros Charm to deal with boardwipes and it makes a decent burn spell.

First of all, Boros Charm is necessary in naya slivers, shock is not. Second of all, naya slivers is bad. Galerider Sliver and Syphon Sliver are just too good to pass up, and the mana fixing options are even better. Chromatic Lantern makes 5 color slivers a no brainer with how much you stand to gain from it.

Alright. I will make it into a 5 color. The way I normally work these decks is to get suggestions of what to take it and put out. I was already thinking of having Boros Charm instead of Shock . This was just a first set using cards I had obtained. IMO Into the Wilds is a little too slow for me and I'd rather have the mana fix instead. I want to run Chromatic Lantern , I just need to obtain a set of them.

My main question remains tho, what should I take out and what should I put in?

I would build an anti-control sideboard 4x Ranger's Guile and 4x Savage Summoning it should stop the enemy counters or direct dmg on your Slivers, i thought about a G/U Slivers deck also, where i control enemy gameplay while i safely play my Slivers with those 2 cards stopping their control or direct dmg....

Maybe some charms would help with the dmg and gameplay the Selesnya Charm ... i would bassically get all instants or sorcerys for sideboard cuz u already have plenty creatures in that deck... hope it helped

U could also add some Trollhide into your sideboard, it protect your creatures also, and make them a lil stronger

Ok, here's what you need to understand about slivers, most people don't get it. You cannot run 4x of a sliver if his ability doesn't stack. So 4x Predatory Sliver is great because each time you put him out all your slivers get an additional +1/+1, however 4x Blur Sliver is terrible because it becomes a 3 drop 2/2 sliver and doesn't add to your board presence in any meaningful way. So to add additional cards, drop anything you're running 4 of that doesn't stack to 3, also Megantic Sliver to 2-3 as well since he's such a high cost. That should free up room for Galerider Sliver and Syphon Sliver . Drop Darksteel Ingot and replace with Chromatic Lantern and drop Steelform Sliver since he's just a really bad card and replace with 2 more Chromatic Lantern . Also drop Groundshaker Sliver since he's equally bad. That should clear enough room to make 5 color and should clean up the deck a lot.

This a midrange deck. That means winning between T5 and T8 if your deck is well built. Tribal midrange is even faster by one turn. You're running 4 Manaweft Sliver right? That means that there is a HIGH chance of you drawing one between T1 and T3 , which is when you would need to make effective use of them.

Imagine this:

T1 drop a red scource, and a Striking Sliver

T2 drop a green source, and Manaweft Sliver

Now at this point you have 4 mana available BEFORE you drop a land.

T3 drop a land or not, drop Into the Wilds

Now, with this enchantment in play, you're drawing TWO cards during your upkeep, effectively, not to mention that you can potentially drop TWO lands PER turn.Now you're running away with the game, T6 you have your opponent(s) pinned to the wall with a FULL BOARD! The game MAY last another turn. Unless your opponent Fog s you or something stupid.

Into the Wilds = draw advantage + land advantage

Y U NO USING THIS CARD?!?!?!

My bad, I re-read Into the Wilds it does NOT give you card advantage. Which is unfortunate. HOWEVER, it still DOES help give you land advantage. Thus permitting you to run away with the game. So instead of T6, the game should done by T7, no later, unless they trump you with something like a board wipe. In case of Mutilate my friend suggested Golgari Charm to give your creatures regenerate. At least for your side-board.

not sure if slivers can work in standard, but this might be better Cavern of Souls , Domri Rade , and Descendent's Path.

agreed with Spazik008

Great deck, +1 from me!! Though I think that Steelform Sliver feels a bit redundant. No idea what you could replace it with though so I wont complain!

From playing sliver decks at 3 tournaments now...there a few things I've commented on several sliver decks.

First Door of Destinies and Into the Wilds while being great for a sliver deck, are too slow for competitive standard. You should be more concerned with getting megantic out by turn 4 than bumping all of your creatures up.

I also don't feel that Steelform Sliver and Groundshaker Sliver are worth what you're paying to drop them.

While the trample on Groundshaker Sliver is great, his manacost is the highest and therefore the hardest to get out. Unless you already have Megantic Sliver out you're paying 7 for a 5/5 trampler that gives all your other smaller slivers trample.

And in terms of Steelform Sliver , the +0/+1 just doesn't fit the mold for what an aggro sliver deck is trying to accomplish. I debated it for a while just to deal with small burn cards, but as far as 3 drop slivers go, i'd much rather spend it on blur sliver, or dropping something like Domri Rade .

TLDR: Slivers are a fast paced aggro deck, you can try to mold it into a mid range aggro, but in order to do so you need to find a way to stall early game...which I still haven't figured out a solid way to do. And once Theros comes out, slivers are more than likely going to be extinct once again :( (goodbye to Rootbound Crag , Sunpetal Grove , Glacial Fortress etc)

Consider shocklands like Stomping Ground , Temple Garden , and Sacred Foundry .

They may be expensive but they are very nice to have

I think you're going to want some more Door of Destinies ... maybe even a playset. I know it sounds slightly crazy, but those two Door of Destinies are going to be pretty useless if you draw them late game, when you really need them on like, turn 4.

I disagree Reading_is_cool. Door of Destinies has proven to be way too slow for aggro sliver decks in my area.

Because slivers are a fast aggro deck (not midrange...no solid removal or stall), turn 4 you want to be dropping things like Megantic Sliver , Bonescythe Sliver and Thorncaster Sliver , not Door of Destinies . Building your deck to be strong late isn't going to help if you're dying by turn 7 or 8.

I think you need a playset of Bonescythe Sliver . Double strike is always awesome.

I know many people HATE slivers and think it can't work in standard but I have found if built right can work just fine. As to your deck you need better lands to make it run more smoothly.
