Welcome to tappedout and to Isshin brewing! Great choice for a first deck, he's definitely one of my favorites of the past year. I have a few suggestions to consider as you continue to tune the deck:

• I think you can replace like 3 of your equipment with a few more mana rocks like Talisman of Indulgence and the others in Mardu colors. I mostly suggest this because your deck isn't as Equipment focused, and some of the equipment are mana intensive to cast and equip,

• Reconnaissance is one of the best cards out there for any Isshin build variant. This EDHREC article better explains how Reconnaissance is basically a pseudo-Vigilance anthem, and can prevent combat damage that would be dealt to your creatures. A bit pricey though, but worth it.

• Dolmen Gate - Another excellent card for pretty much any Isshin build. Also a bit pricey, but has had a recent reprinting.

• Breena, the Demagogue - She can be a fun draw engine in Isshin, and has helped me win a few games with how much she can grow threats. Because opponents can benefit from her, they may be less likely to remove her until it's too late.

• Aurelia, the Warleader or Karlach, Fury of Avernus can potentially replace Raiyuu. Raiyuu doesn't have haste like Aurelia, or triggers off you attacking outright like Karlach.

• I think you can maybe replace Chaos Warp with some other removal options that are a bit more versatile, like Generous Gift, Anguished Unmaking, or Wear / Tear.

I hope these suggestions are helpful starting places for potential changes. Let me know if you would like some additional feedback, as Isshin is one of my favorite commanders. Best of luck with your games and brewing!

Crow_Umbra Thank you so much for you suggestions! This REALLY helps me out a lot!

Aurelia, the Warleader is already included in the deck, maybe you missed this? Do you think, cutting Raiyuu, Storm's Edge and adding Karlach, Fury of Avernus is still good? Or should i consider to add something else in this place?

Dolmen Gate is definately a Card i am going to add in the future! I didn't know this was existing^^ Awesome!

All your other Suggestions speak for themselves. Thank you so much!

Oops, yeah I definitely missed Aurelia. It happens lol.

If you want another Extra Combat effect, I think Karlach can def replace Raiyuu for a couple of reasons:

• Karlach triggers when you attack, and she doesn't need to be the one attacking.

• Raiyuu triggers when you attack solo with a Warrior or Samurai. You currently have about 2 Warriors in the deck, and 3 Samurai, including Isshin. From having played Isshin for the past year, you typically want to swing with more than one creature each combat.

I would also suggest maybe cutting It That Betrays and Drakuseth, Maw of Flames. Both of them are very mana intensive, and Drakuseth is very single-color intensive.

I've had a lot of fun with Professional Face-Breaker, which rewards you for going wide & playing aggro. She also pairs nicely with Captain Lannery Storm and any other Treasure production you might have in the 99, since Face-Breaker can turn your treasures into impulse draw.

Ogre Battledriver is also a helpful Haste and power-boost anthem which is pretty helpful in a deck like this one. Vault of the Archangel and AnkleShanker are also both great deathtouch anthems

Lastly, I'd recommend adding stuff like Unbreakable Formation and Clever Concealment as a means of protecting your board at instant speed. Being able to protect your board and maintain aggro momentum is crucial to keeping Isshin chugging along and swinging.

I meant Ankle Shanker on my last comment lol

Crow_Umbra Thank you for the further suggestions and tipps. I really appreciate that! I see that there is more work to do! With this changes I will 100% surprise my playgroup (I am the newest player). Greetz!
