What do you think I should swap out for it? I trying I'll use it in the main deck, it would definetly be useful in the games I play, mostly for indestructible, but even the others could finish someone off if needed. The biggest problem I have with it and the cards like it is what it should replace.

It does help, and I'm willing to change it up quite a bit

The Syphon Sliver helps immensely, IF it gets out, I'm not too worried about letting it go however, and the Battle Sliver , they do cost quite a bit, Megantic Sliver only costs 1 more and gives an additional +1/+3 in comparison, so maybe I should lose them regardless. Right now I'll take out the Syphons and swamps, add two Boros Charm and then experiment the difference between having the Battle Sliver in and out versus having two Boros Charm in and out, if I'm missing the extra punch they give I think Megantic Sliver would be a better choice anyway. Manaweft usually makes the difference between 5 and 6 mana not as big a deal as other decks

Nylea costs about $8 from where I can get it, Groundshaker Sliver isn't my best sliver to say the least, I might just get rid of trample altogether and just have an extra charm

You have to have 4x Ready / Willing , card is freaking awesome with Manaweft Sliver . Tap all your slivers to untap them and give them indestructibility, plus if you have enough slivers you can also get lifelink and deathtouch.

Also if you want to be mean Ready / Willing pairs perfectly with Supreme Verdict , just sayin.

yeowch that would be harsh, but again what would be best to trade out for them? Considering what it's being used for Ready / Willing could replace Boros Charm , Supreme Verdict comes in at $6, so I'm a little undecided about that one money wise anyway

Pretty solid. Having fun playing it against my Friday Night Milling deck haha. Gave your deck a +1!

I love me a sliver deck, however I have found the strongest way to play slivers is G/B with Underworld Connections to sustain your deck and Syphon Sliver to sustain your life, all while using things like Putrefy and Abrupt Decay to clear out threats and Golgari Charm to regen your board vs. Supreme Verdict and the like. Naya slivers are faster and more hilarious but less consistent overall from what I've found.

I've remade it, added syphon sliver, though would like a re-look at the deck before adding your other suggestions, because it has changed a bit

play tested the deck against CastleSiege's Friday Night Milling, and the two highest rated standard decks, Advanced Mutology and Perfection of Milling the results where 1-1, 3-0, and 2-1 respectively (myself-theirs)

however I know how to play my deck more than I know how to play yours so some stats/feedback is still greatly appreciated, I would've taken yours more into account except that I got a few suggestions from the forum and added those first
