Koma, Cosmos Serpent is pretty nice to reanimate, offering the ability to turn off stuff, grant itself indestructible, and give resiliency to forced sac by creating a body each upkeep. It's usually big enough to put actual pressure on if you have to keep sacrificing the Coils.

Good deck!

I like the suggestion of Showdown of the Skalds, but you're pretty much splashing white only for 2 copies of Extus, Oriq Overlord  Flip and 4 copies of a very mediocre Sea Gate Banneret. You might as well go full Rakdos (red black) since you really should swap those 4 Sea Gate Banneret for some Forsworn Paladin anyway, and then you'd only need a single treasure or pathway on white to play the front side of Extus, Oriq Overlord  Flip.

You could probably try to squeeze in a Price of Loyalty just because it could lead to really strong turns with all the treasure/sacrifice synergies you're already running. Speaking of which, Skullport Merchant would also be a very nice fit since you don't have much 3 drops in your curve. Maybe cutting a few 1 or 4 cmc cards here and there would make sense too. A few copies of Hoarding Ogre would be the 1st things to go if I was you. Another good 3 drop would Soul Shatter since it's really strong in this meta for cards like Goldspan Dragon, Koma, Cosmos Serpent, various planeswalkers, etc, and you barely run any removal as it is which is kind of odd in these colors.

It's worth noting here that Koma, Cosmos Serpent is legendary, meaning both that you typically cannot have multiples of it and that Mystic Reflection would not be able to have targetted it in the first place.

I have three Koma, Cosmos Serpent on the battlefield and a Mystic Reflection . At the next upkeep, when the three Koma's Coil token are created, can I use Mystic Reflection to transform all of them into target creature, or do they enter after one another because I have to stack the three Koma trigger?

Another way the first mode can be useful is to stop abilities with timing restrictions. Just like how it stops planeswalker abilities, it can be used to stop something like Pyre of Heroes that cannot be activated in response. Typically you'll want to activate Koma, Cosmos Serpent during their upkeep for this type of use.

I also wanted to add to what Polaris said regarding the legend rule. Beyond making a non-legendary copy you can also ignore the rule entirely with effects like Mirror Gallery or Sakashima of a Thousand Faces .

  1. No. When a card uses its own name, it means "this card," not "cards named this." Each Koma would need to be protected by its own activation.

As a side note, normally you can't have two copies of Koma, Cosmos Serpent in play. Having multiple legendary permanents with the same name under your control forces you to sacrifice until there's only one of them. The only way you can do it is with things like Spark Double or Double Major that make nonlegendary copies.

Koma, Cosmos Serpent

  1. The First Abillity doesnt stop the Effect of a Permanent if a Opponent activate it as a response? Or they activate something, so in response with Koma the Effect couldnt be stopped? Then for what ist the first Abillity good on Koma? Can u give me some Examples (better all detailed Examples)? I know Planeswalkers can be stopped I'm right?

  2. If i have 2 Copys of Koma and someone wanna Boardwipe all Creatures, can I use the Second Abillity of 1 Koma to give every Koma Indestructible? Or must I Sacrifice for each Koma separately? Because there stand no Target its say only a Cardname, so I think all Komas getting it?
