Intruder Alarm Discussion

Undead Alchemist + Altar of the Brood can be pretty spicy. If you're willing to buy it (I know it's like $18) Intruder Alarm takes the synergy even further.

Also, just as an FYI you have several duplicate sets of cards in the deck atm, so it's going to give you an inaccurate card count.

Since your commander already has a card-draw engine built-in, some good options for card draw will be ones that take significant advantage of that. Seedborn Muse, Merrow Commerce (which incidentally can be tapped for Kumena's ability), Quest for Renewal, and Murkfiend Liege are the best effects that untap. There's also Intruder Alarm if you want to get a nice combo going. Might as well run Earthcraft at that point so you can play merfolk, untap merfolk, draw cards, untap lands, play more merfolk, and repeat.

gvazdaus,

A little confused as to why you suggested Slivers I already have in the deck and some filthy non-slivers - but Lifeline is truly a curious card. One I've definitely never seen before, so thank you for that. I decided to look up it's errata'd text and just as you said, it is an ability that all opponents can take advantage of:

Whenever a creature dies, if another creature is on the battlefield, return the first card to the battlefield under its owner's control at the beginning of the next end step.

So that "Your graveyard" verbiage simply doesn't exist - meaning like the previously mentioned Intruder Alarm someone else could potentially win the game before me if they make the right play (or I simply make the wrong one). Interesting and fun card - just not necessarily a competitive one in my opinion. For , I need a Paradox Engine (rest in peace my sweet baby) level of impact.

CoBo I really like Quest for Renewal, probably even more than Intruder Alarm. I will likely test these out this week.

Getting value off of Kumena is important to me, and these suggestions could greatly help out.

And I will absolutely take a look at your build!

Have you ever considered Quest for Renewal or Intruder Alarm for more tap/untap shenanigans? also if you wouldnt mind im trying to put together a list for Kumena, Tyrant of Orazca also, would you mind taking a look at my list and tell me what you think? Fish Walker Tribal

I’ve stumbled across Lifeline. My meta has become very small due to the pandemic and for a variety of reasons including Crystalline Sliver and Sliver Hivelord, removal has moved toward sacrifice/exile effects. Outside of Tajuru Preserver which killed the theme, there’s little recourse for recurring Fleshbag Marauder. I understand there’s symmetry, which I remember being a turn-off for you in relation to Intruder Alarm but Lifeline seems to be a sure fire way to keep slivers in play without relying on coin flipping or having Patriarch's Bidding.

Hello, I have some cards suggestions you could consider.

Chulane, Teller of Tales - Not a defender but provides insane advantage if he sticks.

Mother of Runes - Again not a defender but the protection from spot removal is handy

Spidersilk Armor - Free butt padding and some answers to flyers

Crashing Drawbridge - Enables combos - see below.

Aura Shards - Just be mindful of this one as its really powerful but depends on your group. I play against Zur so its incredibly useful to me. Might not be as useful to you.

Intruder Alarm - allows for infinite combos - Overgrown Battlement for example.

Oko, Thief of Crowns - Still powerful. Shouldn't ever be a dead card.

Concordant Crossroads - Just over $20 atm. Allows you to be incredibly aggressive and allows you to ramp with Overgrown Battlement and the like. Combine this, Intruder Alarm & Battlement/Axebane & Arcades &/or Chulane and you should be able to drop quiet a few if not all your defenders. Crashing Drawbridge can sub for Crossroads in a pinch though.

Worldly Tutor/Mystical Tutor/Enlightened Tutor - Pretty self explanatory. Fairly cheap options that add a tad of consistency

Aluren - Combined with Arcades/Chulane and you drop the entire deck into play.
Im sure there is more but this is what I could think of off the top of my head.

In my opinion Explosive Vegetation is not playable in commander. Or any other format lol. Maybe in a lands deck. If you already had all the 2 and 3 mana untapped land spells included.

Have you run this deck in paper? Have you made any changes? I think defensive counter magic should probably be in the deck even in its most casual shell.

Whenever I see simic colors I immediately think of degenerate combos. Infinite mana + Finale of Devastation or Thassa's Oracle lines are my favorite, but I dig the Kiki-Jiki lines.Hyrax Tower Scout Splinter Twin and Combat Celebrant all add to those lines. If you use Intruder Alarm it combos with kiki jiki plus can give you infinite mana with mana dorks like Bloom Tender and Gyre Engineer by bouncing a Shrieking Drake or Dream Stalker kind of like the Ancestral Statue line. If you run Beast Whisperer or Guardian Project or The Great Henge bouncing the Shrieking Drake gets you to a Thassa's Oracle win.
