Isamaru has always been my favorite deck in Duel (French) Commander where it's been considered Tier 1 for several years already. So I know what I'm looking for in his Historic Brawl version. The deck is peak fair Magic while being very competitive at the same time. Put simply, it has game against anything. It seems to be considered Tier 2 by Arena, but it is frankly underestimated.

The deck is taxing the opponent from a lot of angles, and it almost always leaves itself a way out with lots of ways to protect its key creatures and a substantial Flash package that catches MANY players off-guard.

The removal suite is pretty decent and will get the job done most of the time, although when there's a cheap "must-remove" commander on the other side of the table it can be challenging to handle them several times in a row (eg: Kinnan, etc). 

I love this deck. Also don't forget :

• to sleeve the deck using one of the several Dog-themed sleeves like "Every Dog Has It's Day" or "Core Set 21 Mastery Pass"
• to use the Jumpstart "Dog Plains" as basic lands if you don't need the snow mana (I've personally been cutting Faceless Haven to play sweet basics instead but it's a suboptimal decision)

A final note: you won't find any Alchemy card on that list since I don't like Alchemy. But it's a personal stance.

--------------------[ 02 - 2023 - adding ONE (4 change) ] -------------------- 

IN :

• Skrelv, Defector Mite
• Zenith Chronicler
• Ossification
• Annex Sentry

OUT :

• Baffling End
• Remorseful Cleric - good creature but without a tutor like Recruiter of the Guard it's too situational
• Rescuer Shwinga - I like my flash package so it hurts reducing it, but Rescuer was rarely impactful. I might take out Reidane instead.
• In the Trenches

RULED OUT FOR NOW : Sword of Forge and Frontier, Elesh Norn, Phyrexian Vindicator, Skrelv's Hive, Planar Disruption

--------------------[ 12 - 2022 - adding Explorer Anthology 2 (2 change) ] --------------------

IN :

• Brave the Elements
• Mutavault

OUT :

• Thraben Inspector
• Plains - thinking about removing Cave of the Frost Dragon instead as it is very expensive

--------------------[ 11 - 2022 - adding Brothers' War (5 change) ] --------------------

IN :

• Siege Veteran
• Loran of the Third Path
• In the Trenches
• Mishra's Foundry
• Myrel, Shield of Argyve

OUT :

• Intrepid Adversary - the lifelink is decent but it's rarely been the bomb I hoped it would be
• Banishing Slash - it has happened that this card gave me a 2/2 samourai but it can feel awkward at times.
  
• Maul of the Skyclaves - most definitely a very good card that's won me games. I'm a little bit on the fence but I'd like to try In The Trenches in its place since the anthem also provides buffing and it kinda doubles as a removal spell late game. If it's not concluding I might bring back the Maul.
• Tyrite Sanctum
• Anointed Peacekeeper - very decent but it is dealt with too easily and then there's no tax left contrary to a Spellbinder

MAYBE : Lay Down Arms, Recruitment Officer (I can see this as a repeatable more expensive Thraben Inspector. Also one more power), Steel Seraph

--------------------[ 09 - 2022 - adding Dominaria United (3 change) ] --------------------

IN :

• Guardian of New Benalia
• Anointed Peacekeeper
• Serra Paragon

OUT :

• Gideon of the Trials - the most awkward of the planeswalkers in the list. Often you'll want to be +1ing to protect him but then he's not adding pressure and acts as a bad removal.
• Linvala, Keeper of Silence - love her but she's often a 3/4 flyer for 4 with no text. Serra Paragon will create more value.
• Rabble Rousing - love that card but it's happened that it did not help me catch up or felt useless after a wrath. It's still a fun one overall.

A few nombos to be aware about:

- Containment Priest + Ajani's reanimation or Containment Priest + your creatures coming back from under Restoration Angel. However Containment Priest is great with Sigrid and Fairgrounds Warden.

- Colorless Lands + Heavy white pips cards (Benalish Marshal)
