Muscle Sliver, Predatory Sliver, Sinew Sliver, all those are better than Frenzy Sliver, and you really should run 4 of each if you want to make this an aggro deck. Ancient Ziggurat is a great land, so is Sliver Hive. You should run Manaweft Sliver or Gemhide Sliver for mana fixing. Crystalline Sliver is very good for keeping your slivers alive. Why are you running Bump in the Night? Run Lightning Bolt instead, it doubles up as removal. Also, why are you running AEtherize?

Your battering sliver is useless at the moment because the only sliver you have that buffs damage is 3 predatory slivers. Add another predatory sliver, and 4 might slivers. You really wont need any virulent slivers, your opponents should be dead long before they reach 10 poison counters. You also don't really need lightning bolt or ajani, grab some sliver legions or sliver queens instead.

If you're going to make this competitive, you can't run lands that come in tapped.

FAMOUSWATERMELON Then what would you suggest?

Well lands that don't come in tapped XD

Shock lands would work well here.

I think Megantic Sliver would work better than Might Sliver. Also, I like the inclusion of Sliver Legion.

Magma Sliver works well, especially with Shifting Sliver, which is good anyway. Also, I think you should add some Sentinel Slivers, 'cause that way there may be very little risk in attacking.

Frodomouth, I originally had Sentinel Slivers, but I just thought they would be useless for an Aggro deck, but I can see where you're coming from. Thanks for the feedback!

If this is going to be an aggro deck, I'd recommend taking out Megantic Sliver, Sliver Hivelord, and Sliver Legion. They're way to expensive to do any good here. Replace them with cheaper options like Leeching Sliver, Sinew Sliver, Diffusion Sliver, and maybe Shadow Sliver or Blur Sliver. Once all your creatures are 1-3 CMC, replace Ajani, Mentor of Heroes, Coat of Arms, and Death Denied with AEther Vial to get more slivers out quickly.

Definitely_Paying_Attention Thank you for the help with the Aggro portion of this deck, as I was at a loss of how I might implement certain cards to play with it in mind. I'm new to MTG, so your feedback is greatly appreciated. Thank you!

Glad I could help. I'm always happy to give advice, though I hope I didn't come across as a know-it-all or anything, I can be that way sometimes :)

Oh, and one more thing- I think Return to the Ranks would be a better version of Death Denied, since all your creatures except Sliver Legion are CMC 2 or less. If you want to recur Sliver Legion, though, keep Death Denied.

Definitely_Paying_Attention It's awesome you take the time to help out newbies like me. Return to the Ranks definitely works a lot better than Death Denied, as I don't think Sliver Legion will need to be played more than once before my opponent is finished. Thanks for all your help!

Not a problem- honestly, I'm still a bit of newbie(returning to the game after a long break), myself, I just kind of have an encyclopedic memory when it comes to MTG cards. If only I could remember the important things so well :)

The only issue i see is your not doing dmg fast enough lose a couple side effects and increase the number of 2cmc sliver lords you want at least 8-10 lords in aggro sliver decks. - 1 Galerider Sliver -2 Striking Sliver -2 Sliver Legion -1 Sentinel Sliver +2 Predatory Sliver +4 Muscle Sliver. That should make your creatures way faster. -1 Ajani, Mentor of Heroes -2 lands with the lower curve you have now and add in 3 Collected Company for the surprise instant speed creatures after the other player board wipes.

Also Reality Shift or Path to Exile are better removal then Lightning Bolt most the time cause they kill problem indestructible and huge creatures.

It's an aggro deck. The bolts are often used as finishers. Granted, Path to Exile may be a good addition, but not as a replacement for Lightning Bolt.

derickmoore25, I have to agree with SpatulonMk3 on using bolt instead of Path to Exile, as the whole point is not to remove the creatures, but just kill the player as fast as possible. derickmoore25, I do appreciate the card ideas you gave me, but with all the changes you have, it would completely change the deck. Again, the deck is for targeting the player and not their creatures. Although, I might make a copy of this deck and implement your ideas later on. Thank you guys both for your feedback!

How about running a couple of Mesmeric Sliver?

Fungreatmario, Mesmeric Sliver is more of a control type creature, and I'm going for more of a buff/aggro deck here. Still a good suggestion. Thanks for your feedback!

Actually derickmoore25 has a point, Path to Exile could be good in the sideboard against Wurmcoil Engine and Batterskull which otherwise shut you down. I wouldn't run more than 2 or 3, though.

Definitely_Paying_Attention I guess that makes sense. I'll put it in my sideboard then.

Definitely_Paying_Attention I wanted to ask you if Venser, the Sojourner would be better than Ajani for a potential planeswalker due to his unblockable ability. What do you think?
