Intruder Alarm Discussion

KALE434 on Primal Slivers

Love the deck got a couple of suggestions though Harmonic Sliver just a Aura Shards on a stick. Maybe Training Grounds if you want your abilities to be cheaper and second copy of Heartstone. A Paradox Engine for another copy of Intruder Alarm to help untap your slivers to tap em again to play another sliver when you have a Gemhide Sliver or a Manaweft Sliver on the battlefeild already. Also i know you wanna keep it permanents only but Crib Swap is to good when you have Sliver Overlord as your commander, since you can find it with its ablity to search for a sliver card. Once again awesome deck!

this deck is slow, very slow. And whit no protection or ramp you are dead vs most decks before you even play a spell.

your fists spell is a 2-drop that don't erect the game in anyway.

go fewer angels, more artifact ramp, 2mana lands. more cantrips. remove all enchantments, MABY keep Intruder Alarm, look for a similar card as Cryptic Gateway so you effectively have 6-8 copys and a much higher chance to hit the combo

Mind Over Matter is the best combo with Azami; it's a must-have. Since you have Intruder Alarm, I think Cryptic Gateway is worth running. It gives you tons of cards and often just wins outright.

I really like Teferi, Mage of Zhalfir. Limiting your opponents to sorcery speed is very powerful -- not only do you not have to worry about other players' spells on your turn, but you can also counter other players' spells without interference. Flash is also really nice -- so much so that I recommend Leyline of Anticipation or Vedalken Orrery. Another great wizard is Glen Elendra Archmage. It's great for preventing your opponents from stopping your win, and just for slowing them down.

Dizzy Spell and Drift of Phantasms are great tutors. Delay is a nice cheap additional counterspell.

I don't like Deranged Assistant because there is a chance you'll mill Laboratory Maniac. Realmwright, Sage of Epityr, and Dakra Mystic seem pretty ineffective. How well does Psychosis Crawler work as a win condition?

I also have an Azami deck: Amazing Azami.

Remove Spreading Seas, Always Watching ,Aquitect's Will and Burnished Hart.

Trade your Fumigate for a Dusk or Fell the Mighty or Retribution of the Meek or Solar Tide.

Drowner of Secrets + Intruder Alarm + Stonybrook Schoolmaster is a combo you could consider. Altar of the Brood also fits in.By using Merrow Reejerey to untap an Azorius Chancery you can achieve infinite mana through a Cloudstone Curio if you have 2 merfolks with cmc = 1 (or cost reducing), so you might want to consider Kefnet's Monument and Sapphire Medallion.Cloudstone Curio would also work for infinite tokens and even infinite mana if you use +Paradox Engine untaps your merfolk and mana rocks whenever you cast a spell. Spell Burst can lock everyone if you manage to generate in mana rocks/creatures, for instance.

+High Tide doubles up your mana for a turn

+Scourge of Fleets

+Inundate

Maybe Blustersquall, maybe Breaking Wave, maybe Faces of the Past (this one combos with Schoolmaster + Altar of Dementia/Blasting Station).

Maybe Retreat to Coralhelm + Walking Atlas + Oboro Breezecaller (infinite mana with a land that taps for 2 mana or simply infinite landfall for Altar of the Brood)

Maybe consider Blue Sun's Zenith since with infinite mana you can draw every card of your deck or force someone to deck out.

Maybe Winter Orb since your average CMC is so low and you'll have ways of untapping stuff (it'll lock everyone else out)

Tidal Force Too expensive id rather the Intruder Alarm -like affects; cheaper/more creatures untapped = more useful

Wall of Frost dont find myself blocking a lot and if i do i just use a clone or Revenant -like effect

Oblivion Sower Not great land ramp for what it is and in a 100 card singleton format searching for a usually 35/100 chance that goes down for each land they have in play this seems kinda bad besides its big booty

Silumgar, the Drifting Death might be good for clearing weenies other than that same as o-sower kinda beefy booty but not a lot else helpful

Arcane Laboratory I don't like stax in non stax decks that nets me advantage only in the form of slowing tf out of my opponents think more Rhystic Study than your suggested "Winter Orb" The other suggestions seem solid ill add them to the maybeboard the only reason I am currently lacking Thran Dynamo & Gilded Lotus is due to the ridiculously broken "my wallet is not bottomless" conundrum. i have like 4 other decks with them in atm and it gets kinda pricy the more of them you need :( (curse you staples that wizards retardedly doesn't reprint!)

Hey there-

I saw you were looking at that 2 year old TCC list, so I thought I'd give a comment directly to you since you're looking to build Sliver Overlord. To preface: I've player Overlord for 3 years in a fairly competitive meta, which is why I'm basically combo Overlord at this point. I've got a few pointers you might be able to use, though, so I thought I'd just leave them.

First, my creature choice and combo lines are explained on my deck, here: Za Warudo! (Sliver Overlord Aggro). If you care about that kind of thing, you can look at that, but I won't be explaining how the combos work since I went into better detail in the description there.

Thing the first: Mesmeric Sliver isn't worth its cost. Sometimes you can stop your opponent from getting something that will hurt you- but the better your opponent's decks are, the higher the odds of them getting something equally as bad or worse (IE, your opponents need to run bad cards in order for Mesmeric to really be that beneficial). I'd recommend removing it for a different Sliver.

Darkheart Sliver seems a little better than Victual Sliver as a sac outlet because it has no mana requirement on the sacrifice. Gain 1 less life for 2 less mana sounds much better, to me.

Card suggestions:Synapse Sliver is a great way to receive a full grip from finishing off an opponent. Highly recommended.

Diffusion Sliver is a nice little defensive Sliver that I think you'd enjoy.

Horned Sliver is reasonably cost and gives your army trample, which can be very handy.

Frenetic Sliver is one that took a while to win me over, but if you're facing down a Merciless Eviction on the stack, a 50% chance to keep your army doesn't sound so bad, honestly. Either way, you tend to win out since your creatures being binned, rather than in the exile zone, is better for a Patriarch's Bidding.

For card draw, Rhystic Study isn't bad. Seedborn Muse is ridiculous with Sliver Overlord: You get to untap your lands, tutor Quick Sliver, and then remind everyone in your play group why Prophet of Kruphix was banned.

Cryptolith Rite is perfectly reasonable to run as it gives you 3 copies of the most vital creatures in the deck for establishing board presence. Chromatic Lantern is going to be a necessity on a budget mana base. Burgeoning is extremely good ramp, and can take the sting out of ETB tapped lands, if you run them, since you'll untap with so much more mana at your disposal. Mana Echoes is absurd, even without Sliver Queen.

The best cards for Sliver Overlord would be Intruder Alarm and Paradox Engine, since they allow you to pull all of your Slivers out of your library, should you so choose, and easily finish an opponent off with Psionic Sliver during the untaps. I explain this synergy in my deck's description, but Overlord + 4 Slivers, one of which must be Gemhide/Manaweft = Grab all the Slivers you want.

Hope this helps. I can offer mana base recommendations, too, but it'd probably be easier to wait until you show what you have.
