Obviously which lands i use will change depending which slivers I keep, but I'm a bit confused as to where to go from here. Any suggestions would be great. Also suggestions for any other cheap cards I could add to really put it over the top would be great. Thanks guys. =)
Also, a thing to keep in mind when deckbuilding is to avoid redundancy. In your case, we really don't need double non-stacking abilities, like Haste, Flying, Provoke, Double Strike. Especially since you have Homing Sliver, which can search for any of these abilities in a pinch. So for the hasting, flying, provoking, double striking slivers, you should only run 1 or 2 of each.
As for the land base...since your deck is mostly creatures, you should use Ancient Ziggurat, a relatively cheap, uncommon land.
Sideboard in Virulent Sliver against life gain decks, Ward Sliver against any mono color deck, Root Sliver against a counter deck, Might Sliver when I need to win quickly, and Amoeboid Changeling against a tribal deck (to possibly take advantage of any bonuses my opponent might be giving to his creatures [Give them to my slivers/take them away from his creatures]). Also the Amoeboid Changeling/Sliver Overlord combo is great for stealing an opponents creatures. (I do plan on dumping more money into this in the future).
You have 11 lands that come into play tapped. I think between your Vivids, Terramorphics, Spheres, and Gemhides that you don't have need of the Coliseums. I would remove those 3 lands for 1 each of Mountain, Forest, and Plains.
I realize my sideboard has too many cards, but seeing as how I play casual I doubt anyone will care. I could actually just remove the Amoeboid Changeling if anyone made a fuss.
Thanks for the suggestion. Since I'm pulling the Talon Sliver, and going with Two-headed/Sidewinder combo, would it be better to pull the Winged Sliver and leave the Harmonic Sliver in? My reasoning would be that since I've already got flanking running, and the bonus from Spined Sliver only helps that, then there isn't going to be much that can block me and survive, so I don't know if the evasion from the Winged Sliver is really necessary. I'd much rather have the destroy artifact/enchant granted from the Harmonic Sliver. Just a thought....I guess I could always sideboard in one or the other as necessity dictates.
The land suggestion was great. I wasn't too keen on having to take damage if I end up getting mana screwed when there are safer alternatives.
My thought is that having your whole team suddenly fly can knock people from double digits to dead in about 0 seconds. However, Harmonic vs Winged is a call that is very dependent on the types of decks your friends play. If you are constantly dealing with troublesome or game-locking enchantments, then having Harmonic maindeck is more important than mass evasion.
That said I'd still try to fit in at least 1 Winged you could slivercycle for.
What do you think of kwong's suggestion of dropping some cards to include plated sliver? I'm reluctant to remove Spined Sliver or Two-headed since they have such great synergy, and Fury sliver was a card I just really wanted to include because i figured by the time I get it out it would definitely spell defeat for my opponent. Is plated sliver really that good as a one drop?
the more 1 or 2 drops that you have that actually do work, the faster you'll win. I was playing my friend with an incomplete countersliver deck and I won most of the time before the 6th turn.
My countersliver deck has a bad manabase, and i have a few grand coliseums in there. If you can't get painlands or dual lands, I'd recommend using city of brass instead. You should be dealing way more damage than your opponent so the one damage isnt that big of a deal since it doesn't come into play tapped. if you fix the mana curves, you can pop in some aether vials, that way your slivers won't be counterable as well.
if you aren't winning by the time you have fury sliver out, I don't think it'll save the game. with the rule changes from m10, the synergy of spined and two headed loses a lot of its oomph since you have to deal damage in order now of blockers assigned. Plated slivers have definitely saved me many a times from various threats lol.
To smooth out your curve I would increase your number of 1-drops, Sidewinder, Virulent and Plated are the three I use in my own Sliver deck. A pretty awesome finisher instead of Titanic Ultimatum is Sliver Legion, he's a Coat of Arms on a stick and a Sliver to boot!
I got a majority of the cards yesterday, put the deck together last night, and played it against some of my other decks, (still missing 6 cards), and thoroughly beat my other decks into a pulp, repeatedly. So thanks for the advice. When I get the final cards, and decide 100% on what I want in there, I'll post it for critiquing. Thanks again.
It's been playing pretty well so far. It's really fast, and pulling a Titanic Ultimatum when the game has gone on too long spells a dead opponent Even if I've got to tap a bunch of slivers for mana. Ward Sliver, Root Sliver, and Harmonic Sliver have been seeing a fair bit of face time.
