UPDATE including mh1 slivers!!!
Sliver Aggro FTW! 1-2 CMC Slivers with AEther Vial to help you cast them as fast as possible. With 8 Sliver lords giving you +1/+1 bonuses and Adaptive Automaton/Phantasmal Image functioning as the remaining one since we don't have Muscle Sliver in modern and Sedge Sliver needs to have a very expensive manabase just to have him around.
MAIN DECK:
1 CMC:
x3
Galerider Sliver
: amazing replacement for
Winged Sliver
. You want this card to hit the battlefield every game.
x4
Sidewinder Sliver
: flanking will make your opponent think twice before blocking your slivers.
x2
Striking Sliver
: First strike is always welcome, but it does not stack that's why I'm running just 2 of these.
x4
Aether Vial
: amazing card for every aggro deck, it will make your deck faster and you can flash in creatures at any time.
2 CMC:
x2
Throne of the God-Pharaoh
: very cheap damage combined with your leeching sliver can result in winning games without attacking your opponent directly.
x3
Diffusion Sliver
: since there's no
Crystalline Sliver
in modern, this one is the best option to protect your slivers from targeted removal. It can stack making it difficult to your opponent to remove a Sliver from the battlefield.
x4
Adaptive Automaton
: Since there is no
Muscle Sliver
in modern and
Sedge Sliver
needs a very expensive mana base just to have him around. This guy will function as your third lord.
x8 Sliver Lord:
Predatory Sliver
&
Sinew Sliver
will turn your little guys into scary big monsters.
x4
Leeching Sliver
: pseudo Sliver lord that will let you do damage even if your Slivers become blocked.\
x3
Cloudshredder Sliver
: amazing replacement for
Heart Sliver
and it gives you evasion.
x2
Dregscape Sliver
: very good card that can give your lords or your evasion slivers a second chance to win the game.
SIDEBOARD:
x3
Harmonic Sliver
: to let you deal with enchantments and artifacts.
x2
Necrotic Sliver
: great card to remove planeswalkers or to stop combo decks.
x2
Stony Silence
: to deal with artifact decks.
x2
Tormod's Crypt
: for some graveyard hate.
x2
Pithing Needle
: to help you with individual threats.
x2
Swan Song
: save this one to counter your public enemy #1
Blood Moon
. If you don't have
Aether Vial
or
Manaweft Sliver
out that card can make you lose the game.
Please help me with suggestions to make this deck even better.
