Intruder Alarm


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

Whenever a creature enters the battlefield, untap all creatures.

legendofa on Cube idea, good or bad? …

2 weeks ago

I've had this thought for a while now, and I haven't done anything with it, so now I'm making it everyone else's thought.

Ante cards like Darkpact are banned in every sanctioned format, because they come dangerously close to breaking gambling advertising laws, and have a high risk of feel-bad moments in general. In a cube, though, all the cards go back to the same box at the end, and "ownership" only lasts as long as game night, so there's no stakes or permanent loss of cards.

To add to the ante antics, and use more cards that can't reasonably be used anywhere else, the Conspiracy cards and Draft matters cards like Backup Plan, Smuggler Captain, and Cogwork Spy could fit well into a cube, since the whole purpose of a cube is to be drafted.

The final element of this cube idea is to sprinkle in some two-card "you win" combos, like Sunbird's Invocation + Approach of the Second Sun, Plunge into Darkness + Near-Death Experience, Biovisionary + Rite of Replication, or Chance Encounter + Frenetic Efreet. These should provide a little treasure hunt for the draft. I would like to keep these all 2+ colors and 6+ total mana value, to avoid making them too easy to reach (numbers are arbitrary and open to consideration).

Would this be an interesting cube to draft, or would it just be too complicated? My goal is to get some mind games going for those who want them, while still allowing for a more straightforward draft. My concern is that using too many of these gimmicks will end up in decks that are flashy, but lack fundamentals.

Intruder Alarm can help you get more untaps and mill for your creatures. Could cut Staff of Nin for it, maybe.

Nice build, I’m working on a similar one.

What are your thoughts on Abundance, the downside is you lose the card draw as it says put into hand but it does let you get the land to out into play if you have none in hand.

I must say i like the kodama combos, I hadnt thought of that. Ive gone for more of a combo around Living Plane effects with Intruder Alarm and Field of the Dead

+1 form me :)

nhhale on Can I tap creatures between …

Suppose I have Arcanis the Omnipotent and Intruder Alarm on the battlefield. My opponent taps Krenko, Mob Boss for 10 goblins. There are 10 triggers on the stack, not just one (this is confirmed on scryfall). Can I tap Arcanis in response to each of these triggers, effectively drawing 30 cards from this interaction?

Follow up: Suppose I also have Naban, Dean of Iteration on the battlefield and I cast Cursecatcher. There will be 2 triggers on the stack this time, so if the logic of the previous example holds up, I can draw 6 cards. Am I correct here?

I'm also looking at building an Urtet deck, and this deck is a masterclass in flexibility already, even while lacking the likes of intruder alarm.

I think Temur Sabertooth is just there for general value plays, same as with Crystal Shard. If you have the mana, you get at least one extra ETB per turn, and that seems to be the primary mode of play for this deck: Not to go high, but to go wide, to do the shake-n-bake boardstate.

As for Intruder Alarm, it's a great value piece, but only in a meta that doesn't mind solitaire'y plays. This last bit is what makes it less fun for filmed content, where people generally will wanna see quick and splashy plays, and not the endless repetition of "Cast this, trigger that, repeat" for 10 minutes. This can be said for Urza and Thrasios as well, especially combined with Mana Echoes, but not to the same extreme.

As for the absence of artifact lands, I think it is cause of the recent ubiquity of artifact sweepers, in response to how powerful and plentiful treasures have become and how frequently they've been printed/reprinted. I have a fair few artifact decks, and it flippin hurts when half your lands are gone because someone throws down an artifact sweeper. The slight advantage it gives to your artifact count is hardly worth the risk of losing half your lands to a board wipe, unless you run a lot of recursion as well so you can rebuild quickly and efficiently.

raincoat on Knowledge & Power - Alaundo Haymakers

Love this deck. Any reason for not running Intruder Alarm?

Have you found it too enabling for other decks, such that Alaundo never gets to capitalize off of it enough? Had a game the other night with this deck & the friendly neighborhood Shorikai, Genesis Engine player dropped an Intruder Alarm. Alaundo receiving numerous free untaps allowed me to snowball the game & cheat out Omniscience + plenty of draw to pull three counterspells, winning the game on my next turn. Thinking of including Intruder Alarm in this deck just because of that, but I can see situations where it can enable other players to out-combo you.

Either way, very fun deck - great work!

Im not sure if I can edit my first post so I will say this, one of the best cards in any Chulane deck is Intruder Alarm generates insane value not only with chulane but other etb draw with cards like Guardian Project and Beast Whisperer
