Hidden Retreat and Penance would allow you to streamline your mana base and make the deck less clunky. Also Dust Bowl.

Harsh Mercy tribal destruction.

This deck desperately needs haste. I see your creatures are streamlined so no Anger but an artifact, enchantment and/or land seems crucial.

Thanks for stopping in prophet of profits.

I too love Tsabo. I think the high CMC scares people away but there is no denying that this is a powerful card well before the power creep.

Extra activations = Patriar's Seal, Puppet Strings, Magewright's Stone + Staff of Domination

No you are right Spreading Plague is necessary.

Crystal Chimes Urza was the "enchantment block" after all haha! Good eye. Definitely useful.

I would statistically get better mileage out of both Jet and Ruby and I will be updating the deck to be more efficient based off your observation. That said... Heartless Summoning is a pet card of mine. I love that permaSol Ring. It turns 3 drops into 1 drop weenies and it turns 4 drops into hate bears! Tsabo 6/3 @ feels good.

Hall of Gemstone and Hum of the Radix

Definitely a serious possibility. Is Thawing Glaciers better in this strategy?

Sneak Attack!

Industrial Advancement recycle your dragons. Easy cut Bloodshot Cyclops

Magewright's Stone and/or Thornbite Staff engine fuel.

Honor-Worn Shaku

Sword of Truth and Justice

Norn's Annex

Ward of Bones

Savor the Moment

Oath of Teferi

Oath of Teferi

A few of the Vraska planeswalkers seem good in here.

Cut some creatures, the creature tutors and Reanimate.

Squee is PB&J with Survival! Guarantees a creature coming down once a turn.

Dualcaster Mage this is a solid suggestion!

Not enough life gain to warrant Alhammarret's Archive.

I didn't think about extra combat steps but it is the best way to abuse the commander. I will be cutting 4 creatures for some extra combat steps.

Fanning the Flames reusable.

Thousand-Year Elixir and Thornbite Staff abuseable.

Memory Lapse + Lapse of Certainty

Scorched Ruins + Deserted Temple

Gigadrowse!

Sunstrike Legionnaire and/or Ballynock Trapper = Hylda Goblin Sharpshooter

Nice deck. A bit heavy on creatures? You need a few more Dimir tricks.

Ideas Unbound, Windfall and/or Dark Deal big card draw

Deep Analysis little card draw

Increasing Ambition big tutor

Mystical Teachings little tutor

Dark Withering great removal

Circular Logic great counterspell

Forbid and/or Demonic Collusion forever

Null Brooch > Negate

Reanimate vs. Shallow Grave... Is access to potential green/white ETB/static effect a better investment than a guaranteed hastey beefy beater? I'll chew on it.

No Urborg because no Coffers or swamp walk.

I liked Vault for the global death touch. Lifelink was just a cherry on top. It does seem a bit over priced for something that is more cute and not game winning. I'm brainstorming an upgrade in utility.

Dragon Tempest > Hammer of Purphoros

Your suggestion got me thinking... Whip of Erebos. Potential Kaalia #3 and adjacent to Entomb. Clean swap.

Haha wow you are right. I never really digested what it is doing. 3 life for 1 colorless with an IF trigger. Perma haste... It's hard to argue with you because it's crucial to this strategy but Mardu needs color mana so badly. If this strategy was running Urborg I wouldn't be questioning your suggestion.

Entomb is the last piece of the reanimation shell that remains. Corpse Dance is Kaalia #2 in this list. Reanimate is probably going to get upgraded to Shallow Grave again. All that said, I'm not sure if I'm running enough graveyard centric cards to support it anymore.

I gotta be careful with the enter play tapped lands, especially ones that don't make mana. Kaalia is in 3 colors that aren't particularly rampy, although white has been getting support in recent years.

I would never pay for Anger ;) it would be Entomb target #1

All 3 commander instants have been in here at some point and all will return once I figure out the correct balance of utility.

General's Kabuto is doing what I need better than Dolmen Gate. Cut.

Mudslide is just tech. Every single creature in the list has flying. I doubt my opponents will have a similar percentage.

Bedlam is grossly underutilized. Not quite Moat but still something. Perfectly captures the Mardu spirit: anarchy. That'd what Kaalia represents to me so I tried to use it.

Insidious Dreams was for late game stacking. Discard 2 or 3 to guarantee finding the right finishers. Might leave the deck too vulnerable.

Isshin, Two Heavens as One clearly has a useful trigger but doesn't have flying.

I'm running Flamekin Village over Hall of the Bandit Lord because it makes mana. Footfall Crater is a solid card. Haste when you need it or cycle away. Perhaps Anger instead?

Machine God's Effigy and Misleading Signpost

Mikokoro, Center of the Sea

Echo of Eons

If Jin-Gitaxias, Core Augur makes into the main deck you have a playset of big spells to cheat with Show and Tell

Really like this shell. Corpse Dance and Sneak Attack are pet cards of mine and this is a great home for both!

Urza's Saga get dreadnought or your ring.

Hall of the Bandit Lord and/or Flamekin Village haste is useful in a pinch.

Riptide Laboratory commander protection.

Demonic Collusion neat discard outlet.

Prismari Command and/or Kolaghan's Command really neat swiss army knives.

Jaxis, the Troublemaker and/or Saheeli, the Sun's Brilliance on theme.

Seshiro the Anointed useful with the tokens.

Leering Emblem and Livewire Lash prowess-esque pump.
