Intruder Alarm Discussion

Doombeard1984 on The Invasion is Coming

Hi there. So I have a sliver deck too, and it's great fun to play... Maybe not for everyone else, but that's not really my problem right? Lol. Have a look on my profile, it's on there.

So there is definitely going to be a +1, because slivers! For the hive!

So some suggestions maybe:

  1. Skyshroud Claim would enable you to get 2 of you shock lands and help fix you for mana, as it searches for forest type. Obviously fetches would be good, but they are super expensive.

  2. Some non Exile based boardwipes could be a good plan. You have Sliver Hivelord, so destruction effects are just fun. Classic Wrath of God, Blasphemous Act is fun in conjunction with Spiteful Sliver and you can even look at mass land destruction, as your slivers will be able to produce mana.

  3. Morophon, the Boundless could be a good shout for your build, as yours is a much more creature heavy, less combo based build.

  4. Some real good enchantments to help are Mana Echoes and Intruder Alarm. Can make you have real explosive turns, and in conjunction with haste and mana production slivers you have the chance to tutor and play your whole deck with Sliver Overlord. Depends which way you want to go though.

  5. There are better versions and more utile slivers you can use. Just having a look on mtg gatherer can help you find potentially more efficient versions of the slivers you have.

  6. I think maybe there could be room for more targetted removal. Path to Exile, Utter End, Vindicate, Terminate. The list is huge. Sometimes that spot removal can help you in a pinch.

  7. Patriarch's Bidding is fantastic. Bounces you back from a boardwipe. Is a bit pricey though.

Hope this helps and rock on!

RNR_Gaming Okay, time to go over some of my other ideas I haven't fully fleshed out!

Oros, the Avenger Super weird commander that I think has some pretty powerful text. Obviously not super cEDH, but with something like a Basilisk Collar, it feel really busted, go for a (generally) one-sided sweeper, gain 3 life for each one killed xD. Not the most powerful, but really cool card I haven't even seen played in any game of Magic.

Tymna the Weaver/Sidar Kondo of Jamuraa These two have some amount of powerful synergy I think matters a lot. Using a clearly creature based strategy that should be able to get your 3 tymna draws each turn can be used for casual or competitive, and I think you could go for hatebears or not, since any dork and your commanders just gives you so much draw power. After that you could be running anything xD

pheldagrif I think a deck based around this and Intruder Alarm would be really spicy, I don't know if possible, but using that, with an effect like Bloom Tender is infinite mana, tossing in a Suture Priest is a GG, also, bant means you can use effects like Flash Hulk, or if you give infinite creatures out, Reins of Power can win too, swinging for an infinite win. I don't know how to use the rest of the deck though, cool concept imo!

Zacama, Primal Calamity is a sweet combo enabler, using Temur Sabertooth you can go infinite pretty easily, and with the Dockside Extortionist combo in the format too, I don't see why that deck wouldn't still have good backups, especially with Sanctum of Eternity comboing with it too, you could use a mass of creature and land tutors, attempt to have a super controlled combo, but then also have a super high value commander that can crush in stalls, and can stops most other combos when it sticks outside of consult and flash, like Yisan, Kiki lines, etc. all die to it, and so much of staxy hate pieces fall to it too. Just keep your eyes open for cursed totem and I think you'd have a powerful list!

CrimsonWings3689 on Deck does not contain a lapdance *ding* Sliver EDH

@Mortlocke - I suppose it's a matter of differing opinions. Were the deck more geared towards the pure aggro route, sure, you might be better served with other slivers in place of something like Diffusion Sliver and/or Unsettled Mariner. If your route is for combo, you being able to protect your pieces is paramount. Until they print a Hexproof granting sliver, you have things like Diffusion, Crypt, Unsettled, Crystalline, Hibernation and Hivelord. The built in tax effect or innate protection offered by the slivers mentioned extend to the rest of the board. Suddenly, your opponent has to pay well beyond what they'll ever have with X spells to target more than one of your slivers. Suddenly they have to devote their entire turn to taking one of your pieces out instead of advancing their boardstate at the same time. That's not even to mention other options like Heroic Intervention that can add additional protection to your strategy.

If your intent is to combo off and win by turn 4-6 under ideal circumstances, only super solid starts with fast mana will even let your opponents get to the point of being able to pay for the tax.

Additionally, each of them, being a sliver, counts for combo related pieces like Mana Echoes, Intruder Alarm, etc. Tax effects can warp games - suddenly something like a Rhystic Study or Blind Obedience suddenly makes opponent's play more awkward and forces them to play around it. Unsettled Mariner suddenly forces additional resources to be spent on forced discard, sacrifice or burn effects targeting you, nevermind spot removal for your board.

You're not always going to have Sliver Hivelord or Crystalline Sliver out, and you need to be able to make sure that you can make it to where you get them on board. I would argue that a single counter spell in hand vs a table of 3+ opponents with potential spot removal isn't going to pan out any better than taxing them 2 with something like Diffusion Sliver in the early game.

Dont forget infinite ETB, infinite life, and opponents losing infinite life in the same combo:

Intruder Alarm + Cauldron Familiar + Witch's Oven + Animating Faerie.

Play Witch's Oven, then turn it into a creature with Animating Faerie, then play Intruder Alarm, then sac Cauldron Familiar to the oven.

Oh, and one more thing. Paradox Engine has been banned for sometime...I know...i'm sad too. But a viable alternative could be Intruder Alarm if your deck was more creature based. Have you considered Dream Halls?

Lets get this combo done right. Undead Alchemist + mill = zombies. Perfect! CMDR + zombies = 2 milled which could equal more zombies. But wait right there good sir. Mill gets more zombies but what if we could mill more for getting more zombies. Well a card exists. Altar of the Brood makes it so you:

mill, get zombies, mill for zombies gotten, which could get more zombies. tap all to mill to make more zombies, which mills more to make more zombies which mill more.

But wait, for $19.99 (not actual price) add in two cards, Thousand-Year Elixir and (this is a weird one) Intruder Alarm now we:

mill, make zombies, mill for zombies, tap all, mill, make zombies, mill, untap everything. repeat a semi loop of mill and creation. it "never" ends

Wouldn't Intruder Alarm be a staple in Vannifar decks?
