Matzizzet on Every Masochist Needs a Marchesa to Love Them

Have you considered adding a Trinket Mage and Tribute Mage engine?

Trinket Mage can grab The Ozolith, Skullclamp, Iron Apprentice or Sol Ring and the Treasure Mage can grab you Metallic Mimic, Agatha's Soul Cauldron, Spellskite, Lightning Greaves or a free sac outlet with Altar of Dementia or Spawning Pit *list*. Both mages can also be tutored with Imperial Recruiter and they share the human wizard type with Marchesa which really powers up the Metallic Mimic.

I love Gift of Doom with Crypt Rats, I'm not sure if you have other synergies, other than using it's morph cost to protect your Commander?

Maybe Altar of Dementia in case someone casts a Farewell? I get that the rats will shrink as you sac more rats, but that's still a lot of mill to punish the guy who killed your furry friends! It can also be used to finish someone off that you can't attack due to pillowfort or Stax.

That just made me think of something else that'd synergize with your high power creatures, Mask of Griselbrand can turn a single big Rat into a life gain engine, and if someone tries to kill the rat you can draw a ton of cards, and you still have the equipment. It's also a great way to draw some bulk cards if you equip a big rat and use your Commander on them!

Cloudy2024 I didn't even consider Ancient Stirrings to be honest. it fits quite well, especially because I am considering another playset of a sac outlet like Spawning Pit *list* or Altar of Dementia. A bit of a shame that it does not find anything else but these artifacts and lands, but I will for sure try it, thanks!

Thanks, capwner! Surgical Extraction type cards are definitely something I didn't think about. I most likely wouldn't add it or Extirpate because this list is more expensive than I'd like, but I'll for sure take a look at this style of cards.

As for your deck, I'll comment there so it gets people to see your deck a bit. With a quick glance though, it seems you're focusing too much on just making a lot of slimes and attacking while not having much in the way of versatility. Altar of Dementia would give you another wincon that's not combat in case your opponents end up with something like Propaganda and/or Ghostly Prison.

BirdieGirlie, I remembered two creatures that probably would be very funny for this kind of deck, Lumbering Megasloth and Hierophant Bio-Titan.

Flarhoon13 on Lazav and Gyruda (Companion): Doom Mind

1 year ago

May 3, 2024, I started a new quest. Having built 52 decks, I endeavoured to play them all, in roughly the same order as I created them.

Aug 15

Lazav and Gyruda (Companion): Doom Mind win, long game vs Evan's The Fifth Doctor, Rob's Bruenor Battlehammer and Blaine's Gods, bringing my record to 22-26-1. Bringer of the Last Gift finally won a game after my early Vilis, Broker of Blooddrew me a ton of cards, like 20, plus Kairi, the Swirling Sky held down the fort; and a late Altar of Dementia for self-mill sealed the deal for Bringer of the Last Gift to bring out an overwhelming number of powerful creatures. Win percentage goes to .458
