easy, just make Koma, Cosmos Serpent your commander, then add some ramp.

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?

I just put together a deck of my own with Koma, Cosmos Serpent , Serpent of Yawning Depths and Arixmethes, Slumbering Isle . I also added Arcane Adaptation so everything in the deck comes out as a Kraken, Serpents, etc. Which makes Nadir Kraken all the more fun too.

No Koma, Cosmos Serpent ? You get two 3/3's each upkeep if the twins are around.
