Intruder Alarm


Creatures don't untap during their controllers' untap steps.

Whenever a creature enters the battlefield, untap all creatures.

Wabbajacke on Phenax of the Many Mills

I think with black you have a few better ways to interact with the whole Mill-Theme. Some cards like Geth, Lord of the Vault make use of good artifacts and creatures milled by youre opponents.

And some other thoughts: Sewer Nemesis can get strong really fast. Dread Summons builds an army out of nothing (and you can use them with Phenax). Dreadhound ping like Konrad. Court of Cunning brings in monarch and brings consistently mill. Belltower Sphinx budget friendly protector and Phenax friend. Fractured Sanity hits every opponent and doesn´t care about hexproof

Not so budget friendly options: Intruder Alarm might be very strong with Phenax. Zellix, Sanity Flayer a great way to build some bodys for protection/Phenax and will trigger very often. Bruvac the Grandiloquent doubles mill.

Oh and what else comes to mind Zellix, Sanity Flayer with somthing like Hedron Crawler and Intruder Alarm never ends if youre opponent mills a creature.

Nice deck! I like to see Earl of Squirrel getting some play :) Have you thought about Intruder Alarm and Dryad Arbor? It would require a blue splash (and some money), but with Squirrel Nest it makes infinite squirrels. One of my favourite combos from back in the day :)

I'd recommend Peregrine Drake - gives infinite mana, card draw, and land ramp with Intruder Alarm and Chulane (needs 3 open mana in addition to Drake cost to activate Chulane once).

I don't necessarily like adding cards just because they're infinite combos, but the Drake IMO feels a bit more of a natural choice for infinite combo here than the DramaScepter combo, since it also synergizes with your commander for, at worst, a free card and land drop for 3. The Scepter is only used with 3 cards in your deck (that you don't have tutors for, unless I missed something).

With that said, there's of course nothing wrong with running both combos in your deck, I just am afraid Isochron Scepter will be a dead draw a lot of the time.

Also another not-necessarily-combo card that would be amazing here: Rest in Peace. Synergizes with the mill strategy to prevent you from unnecessarily empowering reanimator decks, and since you don't use recursion...

So, if you are looking for the most amount of squirrels then you can go infinite. (You have to splash blue to do it but) Scurry Oak + Intruder Alarm (I prefer the deck's current strategy because I don't like infinite but if you want the most)

legendofa on Need a good card that …

((Cathars' Crusade or First Day of Class or Celebrity Fencer or Hamletback Goliath)) + ((Elemental Mastery or Kiki-Jiki, Mirror Breaker or Splinter Twin or Krenko, Mob Boss or Thraben Doomsayer)) + Intruder Alarm goes infinite for tokens and +1/+1 counters. There's no particular synergy with Hinata, Dawn-Crowned, though.

I don't agree about Jodah, Archmage Eternal or Fist of Suns. I think both of those cards actually hurt your deck instead of help it. Your mana costs are not high enough for replacing them with WUBRG. Neither of those cards brings what Morophon, the Boundless does to the table. I would dump Fist of Suns for Fellwar Stone or something like Cryptolith Rite. Even Birds of Paradise or something similar is a way better card for this deck than either of those. I would dump Winged Boots for Lightning Greaves. Haste is better than flying and shroud is better than ward.

You have way too few slivers in your deck to "Swarm" anyone. Let alone a table full of opponents. Your deck also has a lot of cards that are targeted creature removal. I would dump a lot of that removal for adding quality slivers that provide removal or create removal for you. Take a hard look at your sorceries and instants and see if there is a sliver that does the same thing. Then replace that card with the appropriate sliver. You also need more card advantage to refill your hand once you start slamming slivers down. You can combo using your mana slivers, Intruder Alarm and cards like Vanquisher's Banner. With those cards in play, every time you cast a sliver you will draw a card and untap your slivers which can let you chain through your library in no time.

For more card advantage and more slivers I would suggest the looking to add some of the following depending on your budget; Herald's Horn, Icon of Ancestry, Cryptic Gateway, Descendants' Path, Guardian Project, Kindred Discovery, and The Great Henge. Since you don't have Sliver Queen you can make more slivers with Maskwood Nexus or Birthing Boughs. Realmwalker is another great card. Adding 4-6 of some of these will really speed your deck up.

Good slivers to replace sorceries, instants or land you take out:

Necrotic Sliver, Essence Sliver, Two-Headed Sliver, Fury Sliver, Belligerent Sliver, Galerider Sliver, Bonescythe Sliver, Venom Sliver, Syphon Sliver, Diffusion Sliver, Hibernation Sliver, Brood Sliver, Crypt Sliver, Blur Sliver, Opaline Sliver, Toxin Sliver, Tempered Sliver.

You don't have to use all of these but some of them are insanely good like Necrotic Sliver. You don't need any removal spells if you have a bunch of slivers and this one in play.

CrazyDanPsycho on Kawarimi no Jutsu

Yeah, nevermind Intruder Alarm. I talked with a couple friends, and have come to the conclusion that it'd be a waste of mana...

What is the general concensus on Intruder Alarm? With creatures ninjutsuing into the battlefield (hopefully) on each of my turns, it would be like a pseudo-vigilance...or am I overestimating the card?
