Intruder Alarm


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

Whenever a creature enters the battlefield, untap all creatures.

penguwave yeah I know it does, thinking about adding in something like Impact Tremors but it’s not as flavourful. Maybe Intruder Alarm would be cool though

Thanks for then upvote and comment :))

Bolt_Snap_Bolt thanks for checking it out. I didn't consider the Intruder Alarm build concept due to my meta, as I play in a large group that runs both cEDH decks and powerful but janky combo decks, which we all try to revolve regularly to keep things fresh...and that card just sets up too many of my usual opponents decks, whereas Aluren always catches them off guard. That said, your build is pretty cool though - obviously not having to stick to 3-CMC or less for creatures gives you a lot more options to work with, especially with the lands-matter concept.

EmEcks feel free to steal the list to your heart's content...that's part of the fun with posting more niche and janky decklists, even when they can be overpowering in many scenarios. Hope you enjoy it, and don't forget to check out the maybe board for more ideas.

adding Prismatic Omen could support Earthcraft + Intruder Alarm and also give swamps for Dread Presence but seems like it would only water down this build of yarok

I think you need one more win condition and some distruption. Maybe going temur will help you. Add Birds of Paradise as an alternative for Iron Myr . I also see a potential combo with Prime Speaker Vannifar and Intruder Alarm but I'm not deep into this yet. I also think that you need some tutors like Chord of Calling that will help you to put less creatures that you need only to combo of. Anyway good job +1.

I was able to spit my entire sliver fleet out with Paradox Engine exactly once. A memorable, glorious way to win and I too lament the ban. I slotted Intruder Alarm in as a replacement, but your comment gave me pause and I agree with you - it's just too risky and relies too heavily on an established board state. For funsies I've decided to temporarily revert to my win-more sliver noob ways and am putting in Unnatural Selection for now.

Question for you regarding The First Sliver - In your experience have you cascaded into a fizzled removal/counterspell very often or do you find your topdeck manipulation suite to be sufficient in that regard? The reason I ask is because I have a similar (albeit much more budget) build to yours except for the topdeck stuff ( Sensei's Divining Top + Mirri's Guile et al). I'm wondering if I need to/should incorporate a few of those options in order to optimize those sweet, delicious cascades.

Hi man. Just a wonder, with The First Sliver what about Congregation at Dawn could tutor up 3 creatures to cascade just an idea. As for Paradox Engine ban, at least we can still use in one on one. I run Intruder Alarm anyway, so can Enlightened Tutor for this and cascade it out. Which seems fair lol. Also was thinking of just chucking Leyline of Anticipation in there as well.

On another note, all the bans hit me lol. Paradox Engine in 2 decks, Iona, Shield of Emeria in kaalia and Bridge from Below in my modern hoogak vine deck. It's been rough lol
